when I try to install nodecellar with Cloudify,I am getting the following error
2015-07-13T17:31:03 LOG <nodecellar> [mongod_a50aa.configure] ERROR: Exception raised on operation [script_runner.tasks.run] invocation

How can I fix this problem?
This exception is raised by the Cloudify Script Plugin you ran a script, which exited with a non-zero error code. Here is the source of that error.
The script that returned non-zero code is that script which is mapped to the configure operation on the mongod node. Which script that is depends on the version of the Nodecellar blueprint that you are using.
I can't give a more detailed answer without information regarding the specific blueprint version, which Cloudify version you have installed, details about your provider (local, Vagrant, Openstack, AWS), and OS (Ubuntu, Centos, etc).

I am facing this issue:
(2006, "Lost connection to MySQL server at 'reading initial communication packet', system error: 0")
on cloud composer on composer-1.16.5-airflow-1.10.14 version, it is an intermittent issue. We have tried cleaning our airflow metadata and modified the code (for example, replacing variable.get() with the jinja template) to reduce the load on db, but we are facing this issue on a daily level. We also restarted the scheduler but the issue started occuring again after two days, also the cpu usage and memory usage graph of airflow database on composer monitoring is constant but the sql database is going into unhealthy state in some time.
The whole error message is as :

There could be multiple reasons as the error itself is too general, so it makes a lot of different possibilities for what could go wrong. Known causes:
Connections are blocked by firewall rules.
This can also temporarily happen while an instance is being restarted.
Generic GKE failures because nodes with airflow-sqlproxy are overloaded.
Since it's an intermittent issue, we can assure connections are not being blocked by firewall rules. We might have to check whether any instances have been restarted. And lastly to avoid generic GKE failures you can upgrade your machine types, allocating more resources.
Also as I already mentioned in the comments you're using an old version of Composer which is out of support from May,2022. Its always better to upgrade your composer to a certain version which will have support from Google .
Given below json:
{ "Model" : "level1" }
what is the right combination of message_filtering_match_values and message_filtering_config values? I try below but it fails:
model_operator = SQSSensor(
task_id='model_operator',
dag=dag,
sqs_queue='https://sqs.somewhere/somequeue.fifo',
aws_conn_id='aws_default',
message_filtering='jsonpath',
message_filtering_config='Model[*]',
message_filtering_match_values=['level1'],
mode='reschedule')
Error message is:

The message_filtering / message_filtering_config / message_filtering_match_values were added recently in PR it was released in Amazon provider version 2.2.0
From the traceback we can see that these parameters are not recognized by the operator which means that you are running an older version of the Amazon provider.
You should upgrade the Amazon provider to the latest version.
pip install apache-airflow-providers-amazon --upgrade
It's also recommended to read the documentation about constraint files.
You didn't mention what Airflow version you are running nor what version of the Amazon provider so note to read the change logs in case you are upgrading major version.
I've completed a manual installation of Eucalpytus 4.4.4 but when I try to use a web browser to reach the eucaconsole (running on the same host as CLC/UFS) I get a 502 Bad Gateway Error.
I'm focusing on this error in the eucaconsole.log What does it mean and how can I update WebOb?
pkg_resources.VersionConflict: (WebOb 1.2.3 (/usr/lib/python2.7/site-packages), Requirement.parse('WebOb>=1.3.1'))

I've edited this post to remove info and focus on the clear WebOb version error.
This issue was solved below. Adding a note that the downlevel python-webob version is actually a requirement of the midonet client installation. So if you expect to run VPCMIDO and have the midonet gateway on your CLC you'll have to run your eucaconsole elsewhere.
This was resolved by removing an older python-webob package to ensure that the newer python-webob1.4 package from epel was used.

Selinux problem. Run the following in the your CLC/UFS machine
setsebool -P httpd_can_network_connect 1
Its better to flush your iptables during installation.
I have installed Robot framework 2.8.7 in a solaris server and added sikuli library to it . when tried to run demo script "Hello world" i'm getting the following error.

I have done the same setup on windows machine and it is working fine. Python version used in solaris is 2.6.Can you let me know how to resolve this?
Thanks
I'm trying to install applications on windows server 2012r2 minion. Namely I'm interested on MS management and .NET frameworks. I can install apps like winscp and firefox successfully, so basically it should work.
Install of .NET (dotnet.sls) gives me this:
# salt 'minion3' pkg.install dotnet
minion3:
----------
dotnet:
Unable to locate package dotnet
.sls points to MS download site, where the actual file can be downloaded.
On the minion side I've got:
2016-04-13 11:41:27 [salt.loaded.int.module.cmdmod][INFO ] Executing command 'Powershell -NonInteractive "Import-Module ServerManager"' in directory 'C:\\Windows\\system32\\config\\systemprofile'
2016-04-13 11:41:28 [salt.loaded.int.module.win_pkg][ERROR ] Unable to locate package dotnet
And asking for the available versions (pkg.available_version dotnet) gives me:
minion3:
The minion function caused an exception: Traceback (most recent call last):
File "c:\salt\bin\lib\site-packages\salt\minion.py", line 1071, in _thread_return

return sorted(pkginfo, cmp=_reverse_cmp_pkg_versions).pop()
IndexError: pop from empty list
None of the other state files I've tried do not give above errors.
So, what is going on and how to correct this?
