Haibo Chen commented on MAPREDUCE-6657: --------------------------------------- Sorry for misunderstanding your previous comments. Do you think we should create a subclass of RetriableException for this instead? [~djp] The message is derived from a instance method this.nn.getRole(), and doing string matching is probably not the cleanest way. If so, I can create file a follow-up jira in HDFS and update isNameNodeStillNotStarted() when we have the new 'NameNodeNotStartedException' that extends RetriableException. > 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 > > > 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.

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
