You'll have to view the logs of the YARN node running the executor, it's not very obvious how to see the logs in the YARN console. If I had to make a wild guess, I would say the user you are running the job with doesn't exit in the node running the executor. ... View more

Should be something like this:   #Start the command line and connect to any of the zk servers # if you are not using CDH then the command is zk-cli.sh #if your clluster is kerberized you need to kinit before, otherwise the delete will fail zookeeper-client -server localhost:2181   #Once in the shell run this to delete the directory with metadata rmr /hbase   ...

If restarting the master din't do anything I would say the hbase znode is messed up in zookeeper. If you have nothing to lose stop hbase, delete the znode in zookeeper, delete the hbase folder in hdfs and start hbase. ... View more
