[jira] [Resolved] (MAPREDUCE-6159) No log of JobHistory found in all logs files

Jason Lowe resolved MAPREDUCE-6159.
-----------------------------------
    Resolution: Invalid

The JobHistoryEventHandler is code that runs in the ApplicationMaster rather than the job history server.  You'll find those log messages in the AM logs of individual jobs which are either aggregated to HDFS (by default) or left on the nodes the AMs ran on if log aggregation is disabled.

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: jobhistoryserver, mrv2

> I intend to dig into 'mapreduce.jobhistory.intermediate-done-dir' argument, the position of which is at `JHAdminConfig:73`, to get some comprehension on history server. This argument is referenced at `JobHistoryEventHandler.moveToDoneNow()`, where history server moves job summary file 
> from "$[yarn.app.mapreduce.am.staging-dir]/$[user]/.staging" to "$[mapreduce.jobhistory.intermediate-done-dir]/$[user]". 
> The following code snippet in `moveToDoneNow()` will definitely write some logs out to log file, but I can found no any sign of it in all logs in $HADOOP_LOG_DIR via command `grep "Copied to done location" *`.
>     if (copied)
>         LOG.info("Copied to done location: " + toPath);
>     else 
>         LOG.info("copy failed");
> Is there anything that I missed?
