unable to start yarn standby resource manager

avatar

from some unclear reason we cant start the standby resource manager (YARN)

actually when we start it its stuck , and from the ambari GUI progress bar its stuck on 10%

to check the helth of the yarn ( standby resource manager )

we want to check the following commands

$> su hdfs

$> hdfs fsck /

what kind/type of errors / warning from the commands we need to search in order to understand why yarn standby resource manager is stuck on start-up

or maybe other verification?

ambari-server restart , then we could start the standby resource manager

@Michael Bronson,

hdfs fsck will check for corruptions in the file system. I'm not sure if that will help in identifying the error for stand by resource manager. Can you please attach the resource manager logs under (/var/log/hadoop-yarn/yarn/ ) folder.
