I am new to Clickhouse and am experiencing difficulties connecting R to Clickhouse.
con <- DBI::dbConnect(RClickhouse::clickhouse(),host="srv-clickhouse",username="user",
password="pw")
This returns the error
Error in connect(config[["host"]], strtoi(config[["port"]]), config[["db"]], :
DB::Exception: default: Authentication failed: password is incorrect or there is no user with such name
There definitely has to be a user by that name and password which leads me to believe that I've done something wrong while at the same time I'm not sure what I have to put into the host part of the address, nor the port nor in the beginning. Should I add the full URL to the host part? Right now I'm using RClickhouse but my database uses the port 8123. Is there any kind of proper documentation and how to solve this issue?
Thanks

Getting this error.
Details: "ODBC: ERROR [HY000] [Snowflake][Snowflake] (4)
REST request for URL https://jaa09657:443/session/v1/login-request?requestId=5bcbbadc-39d9-4271-9bf3-52393e2539af&request_guid=e145e6e8-502b-40c3-b7f2-4164dfbe6fea&warehouse=COMPUTE_WH failed: CURLerror (curl_easy_perform() failed) - code=5 msg='Couldn't resolve proxy name' osCode=2 osMsg='No such file or directory'.
I think the issue is with your server property, you just have your account name, but you really need the Fully Qualified Domain there. IE:
server=jaa09657..snowflakecomputing.com
Base that on the URL you connect with.
If that does not work, could you provide your entire ODBC config?
I can successfully connect with WinSCP, using given credentials, to SFTP server. But when doing it from java using apache vfs I get error:
Caused by: org.apache.commons.vfs2.FileSystemException: Could not connect to SFTP server at "sftp://username:***#server_addres/".

I have checked credentials and they are exactly same as those when I try to connect with WinSCP. WinSCP can connect successfully, but my java code gets the above error (Auth fail).
Does anybody has some clue what could be the issue?
Public IP range of the machine I am connecting from has been added to firewall exceptions as trusted IP on the other side.
Please help, any ideas are very much appreciated.
Kind regards,

The problem was in the password. It contained % sign which is a special character when passed in URI (like pass%word).
So the solution was doing UriParser.encode(sftpUri) before passing it to manager.resolveFile() method like this (in order to replace % sign of password in URI with its hex code %25):
import org.apache.commons.vfs2.provider.UriParser;
...
String sftpUri = String.format("sftp://%s:%s#%s/%s/%s", configData.getUserId(), configData.getPassword(), configData.getServerAddress(),
configData.getRemoteDirectory(), configData.getFileName());
String sftpUriEncoded = UriParser.encode(sftpUri);
FileObject remoteFile = manager.resolveFile(sftpUriEncoded, options);
I am trying to connect to Hive2 using RJDBC but it failing with "GSS initiate failed". However same things working fine using beeline client. Any idea what may have caused different behavior when running both on same node with same credentials?
drv <- RJDBC::JDBC("org.apache.hive.jdbc.HiveDriver", cp, "`")
following is just for illustrative purpose as I wanted to show what all parameter I am using as JDBC url.
conn <- RJDBC::dbConnect(drv, "jdbc:hive2://node1:10000/default;principal=hive/hive_node#REALM;ssl=true;sslTrustStore=store_path;trustStorePassword=store_password", "user", "password")
log4j:WARN No appenders could be found for logger (org.apache.hive.jdbc.Utils).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
Error in .jcall(drv#jdrv, "Ljava/sql/Connection;", "connect", as.character(url)[1], :
java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://:10000/default;principal=hive/hive_node#REALM;ssl=true;sslTrustStore=store_path;trustStorePassword=store_password: GSS initiate failed
A bit late for you, but... look at that post about the details of configuring Kerberos authentication for Hive/Impala JDBC (note also that "user" and "password" connection args are ignored by Kerberos auth)
The post assumes that you have the password stored in a "keytab" file, and use it to create a private Kerberos ticket. If you want to use the default, public ticket instead, then change the JAAS conf accordingly (i.e. useTicketCache=true useKeyTab=false and no keyTab entry)
And to pass the configuration to Java from your R code, the easiest way is to set the JAVA_TOOL_OPTIONS env variable before anything else bootstraps the RJava initialization
Sys.setenv("JAVA_TOOL_OPTIONS"="-Djava.security.auth.login.config=/Path/To/jaas.conf -Djavax.security.auth.useSubjectCredsOnly=false")
PS: on Windows the path would look like C:/Path/To/jaas.conf (Java converts slashes to backslashes automatically; that's easier that escaping each and every backslash because of the way R Strings interpret \)
Final note: if any jerk tags this with "answers should not rely on links", since the aforementioned link points to another post of mine in S.O., then he/she is really a jerk, and I will gladly tell him/her to his/her face, loudly and with exotic words.
I've tried everything possible, to setup nJupiter.DataAccess.Ldap as the membership provider on our intranet based web application built using asp.net 3.5.
Challenges I am facing:
Not able to authenticate the user using the default login webpart (says Your login attempt was not successful. Please try again)
I tried this code and I receive a COMException : "There is no such object on the server."
var ldapMembershipUser = System.Web.Security.Membership.GetUser("username") as LdapMembershipUser;
if (ldapMembershipUser != null)
{
var givenName = ldapMembershipUser.Attributes["givenName"];
}
I have placed my web.config and the nJupiter.DataAccess.Ldap.config here:
web.config : http://pastebin.com/9XdDnhUH
nJupiter.DataAccess.Ldap.config : http://pastebin.com/WsSEhi98
I have tried all possible permutations and combinations for different values in the XML and i am not able to take it forward. Please guide. I just am not able to connec to the LDAP and authenticate the user or even search for users.
Just looking at your config is unlikely to be enough since I don't know your Domino server's confguration, so my answer isn't an attempt to fix your problem. It's an attempt to teach you how I would approach it if it were my problem. Here's what I do to troubleshoot connections and queries from code to Domino LDAP:
Configure the Domino LDAP server for logging the highest level of debug information with the notes.ini setting LDAPDEBUG=7. See this IBM technote for more info.
Use an LDAP client and figure out how to successfully connect to the Domino LDAP server. I like the free Softerra client for this. Check the logs and save off the info from your successful connection.
Now run your code and compare what you see in the logs against the successful connection.
If the code is making it past authentication but failing on the query, then find the actual query in the log, go back to your LDAP client, figure out what the query should have been, and adjust your code's configuration appropriately.
I am working on IIS 7, SQL Express 2008.
I'm trying to use the Web Site Administration Tool to set up some users in a membership db. I have the tables set up but when I click on the security tab in the web app I get an exception "There is a problem with your selected data store..." the error i get is
"The following message may help in diagnosing the problem: Cannot open database "ticketinventory" requested by the login. The login failed. Login failed for user 'sa'"
The connection string I am using is "data source=kyrian-pc\sqlexpress;Initial Catalog=ticketinventory;Persist Security Info=True;User ID=sa;Password=******;"
(I know to not use sa for a connection string, this is just to get it to work initially and I have removed the password with ** )
I can log into sql with the sa username and password and query the membership tables. If I change the querystring to a fake user name I see the error message in the web app reflect that username so I know it is using the right connection string.
As far as I can tell this should be working but I am obviously missing something. Any ideas?
EDIT
It turns out the issue has something to do with my connection string itself. I created a test page with this code
using (System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString))
{
conn.Open();
conn.Close();
}
and this throws a login exception. For whatever reason my other connection string are being stored in the appSettings so there is some difference that I am now trying to work out.
Despite checking it 5 or 6 times I had the db name wrong in the connection string. Problem solved.
