How can I resolve the exception reported by rocksdb when using NebulaGraph Exchange? - nebula-graph

Question

I want to export data from NebulaGraph and used the configuration file provided by the official documentation.
The core content of the configuration file used in this example is as follows:
# Processing tags
# There are tag config examples for different dataSources.
tags: [
# export NebulaGraph tag data to csv, only support export to CSV for now.
{
name: player
type: {
source: Nebula
sink: CSV
}
# the path to save the NebulaGrpah data, make sure the path doesn't exist.
path:"hdfs://192.168.12.177:9000/vertex/player"
# if no need to export any properties when export NebulaGraph tag data
# if noField is configured true, just export vertexId
noField:false
# define properties to export from NebulaGraph tag data
# if return.fields is configured as empty list, then export all properties
return.fields:[]
# nebula space partition number
partition:10
}
Then I executed the spark task as follows:
./spark-submit --master "local" --class com.vesoft.nebula.exchange.Exchange ~/exchange-ent/nebula-exchange-ent-3.3.0.jar -c ~/exchange-ent/export_application.conf
However, the task fails to be executed, and the following error message is displayed:
org.rocksdb.RocksDBException: While open a file for appending: /path/sst/1-102.sst: No such file or directory
I checked the path and /path/sst/ exists, and I have checked that the permission of this folder also belongs to NebulaGraph.
Could anyone help hint at where I could be wrong?
