I am trying to run a yarn job from a shell script. IF the job fails i should makethe control flow in my script accordingly. IS there a way to get the application id of the submitted job and check it status and proceed further.

hi @ssoldatov, Thanks for your reply. So it wont honour the command line argument if i prvide like this hadoop jar phoenix-4.8.1-HBase-1.1-client.jar org.apache.phoenix.mapreduce.CsvBulkLoadTool -Dmapreduce.job.reduces=4 (not the full command) though i specified 4 reducers, it just considered only.

IS there a way to specify the number of reducers for the phoenix CSV bulk load utility that uses the Mapreduce method to load data into hbase.

How to use the balancer for hbase at a table level. I see that a balancer runs at a cluster level. IS there a wa y to use the balancer at a table level.

I do see the value of namenode handler count set in out cluster as below. <property> <name>dfs.namenode.handler.count</name> <value>800</value> </property> This value is set up by ambari during installation. We have the namenode machine with 128 GB of RAM. Is this value of 800 correct or it is too high

No specific issue on hbase 1.1.2 on HDP 2.5. But since hbase 1.2 is the more latest and since we are doing PSR tests, there was a thought to use the latest version of hbase. Any reason why HDP is still not supporting hbase 1.2?
