Daryn Sharp commented on MAPREDUCE-3911: ---------------------------------------- {{DelegationTokenRenewal}} is used to renew the job's tokens. It will attempt an immediate renewal, but the problem is the first renewal is performed in a background thread that ignores renewal failures. If the first renewal is performed in the job's thread context, then an invalid token will abort the job. I posted a patch a few months ago that fixed this very issue. Unfortunately I'm having trouble finding the jira. > Pending Jobs Metric can get off if job is submitted with invalid HDFS > delegation token. > --------------------------------------------------------------------------------------- > > Key: MAPREDUCE-3911 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-3911 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv1 > Affects Versions: 1.0.0 > Reporter: Robert Joseph Evans > > If a job is submitted, but the HDFS delegation token is invalid, The pending > jobs counter will be incremented, then an exception will be thrown when we > cannot get an instance of FileSystem to read the jobs configuration.
