spark history server - Permission denied

mike_bronson7 — Wed, 01 Nov 2017 11:18:24 GMT

we start the spark history as the following /usr/hdp/2.6.0.3-8/spark2/sbin/start-history-server.sh

from the log spark-root-org.apache.spark.deploy.history.HistoryServer-1-master01

we get many lines like that Caused by:

org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException): Permission denied: user=root, access=READ, inode="/spark2-history/application_1497173286109_0003_2.inprogress":hdfs:hadoop:-rwxrwx---

we try

hdfs dfs -chown spark /spark2-history

but not help not sure if we need to see the folder ?

# ls /spark2-history/ ls: cannot access /spark2-history/:

No such file or directory

please advice what is solution in order to strat the spark history

What user are you starting spark-history-server.sh as?

Do a su spark, before launching shell script. I think you're starting as root user, so it's saying root user doesn't have access to that folder.

Since you've given spark ownership, it should be able to access.

If you must start as root, then give root access to that directory.

@uri ben-ari

Please check which process is using that port which is causing the conflict (If needed the kill that process and then try again)

# netstat -tnlpa | grep 18081
# kill -9 $PID_OF_ABOVE_PROCESS

Hi,

Did you checked what process is running on this port and tried killing the process if required? if the issue got solved?

Thanks
