Unable to start the Yarn resource manager

New Contributor

Hi Team ,

I am getting the below error while starting up the YARN resource manager.

Service ResourceManager failed in state STARTED; cause: org.apache.hadoop.service.ServiceStateException: Could not obtain block: file=/system/yarn/node-labels/nodelabel.mirror org.apache.hadoop.service.ServiceStateException:

Any hints on what to look for or fix it would be helpful



Check HDFS healthy test first.

$> su hdfs

$> hdfs fsck /

@Amith Dsilva - As mentioned by @Peter Kim the issue looks to be on HDFS side. RM is not able to find the /system/yarn/node-labels/nodelabel.mirror file on HDFS due to which its failing to start.
