Datanode automatically stooped after started

New Contributor

I am facing strange issue while starting the datanode using ambari.

It shows started successfully, and than after few seconds, It got stopped, I have tried service restart and all basics things but none of them seems to be worked.

Does anybody have some idea or faced this issue before ?

@Viraj Vekaria

Can you please share the logs of datanode service ? and also the ambari operation logs

Re: Datanode automatically stooped after started

please share the logs from /var/log/hadoop/hdfs/hadoop-hdfs-datanode-*.log

And mean while refer try following steps if this resolved your issue:-

1. Stop the services on that node from ambari.

2. Make sure hostname, iptables, selinux are stop

3. Check ps -aef for each process and kill it from cli [if you are able to see the process running]

4. Start the process from ambari.

let me know if it works.
