Robert Kanter commented on MAPREDUCE-6657: ------------------------------------------ I chatted with [~haibochen]. I think the HDFS change is trivial and it would be silly for us to fix this with the 006 patch, but then have to do it again when the HDFS JIRA is done. May as well do it now. > job history server can fail on startup when NameNode is in start phase > ---------------------------------------------------------------------- > > Key: MAPREDUCE-6657 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6657 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: jobhistoryserver > Reporter: Haibo Chen > Assignee: Haibo Chen > Attachments: mapreduce6657.001.patch, mapreduce6657.002.patch, > mapreduce6657.003.patch, mapreduce6657.004.patch, mapreduce6657.005.patch, > mapreduce6657.006.patch > > > Job history server will try to create a history directory in HDFS on startup. > When NameNode is in safe mode, it will keep retrying for a configurable time > period. However, it should also keeps retrying if the name node is in start > state. Safe mode does not happen until the NN is out of the startup phase. > A RetriableException with the text "NameNode still not started" is thrown > when the NN is in its internal service startup phase. We should add the check > for this specific exception in isBecauseSafeMode() to account for that. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
