> Job History Server has race condition where it moves files from intermediate

> ---------------------------------------------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-7131
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7131
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.7.4
> Reporter: Anthony Hsu
> Assignee: Anthony Hsu
> Priority: Major
> Attachments: MAPREDUCE-7131.1.patch, MAPREDUCE-7131.2.patch,
> MAPREDUCE-7131.3.patch, MAPREDUCE-7131.4.patch, MAPREDUCE-7131.5.patch
>
>
> This is the race condition that can occur:
> # during the first *scanIntermediateDirectory()*,
> *HistoryFileInfo.moveToDone()* is scheduled for job j1
> # during the second *scanIntermediateDirectory()*, j1 is found again and put
> in the *fileStatusList* to process
> # *HistoryFileInfo.moveToDone()* is processed in another thread and history
> files are moved to the finished directory
> # the *HistoryFileInfo* for j1 is removed from *jobListCache*
> # the j1 in *fileStatusList* is processed and a new *HistoryFileInfo* for j1
> is created (history, conf, and summary files will point to the intermediate
> user directory, and state will be IN_INTERMEDIATE) and added to the
> *jobListCache*
> # *moveToDone()* is scheduled for this new j1
> # *moveToDone()* fails during *moveToDoneNow()* for the history file because
> the source path in the intermediate directory does not exist
> From this point on, while the new j1 *HistoryFileInfo* is in the
> *jobListCache*, the JobHistoryServer will think the history file is in the
> intermediate directory. If a user queries this job in the JobHistoryServer
> UI, they will get
> {code}
> org.apache.hadoop.yarn.exceptions.YarnRuntimeException: Could not load
> history file
> <scheme>://<host>:<port>/mr-history/intermediate/<user>/job_1529348381246_27275711-1535123223269-<user>-<jobname>-1535127026668-1-0-SUCCEEDED-<queue>-1535126980787.jhist
> {code}
> Noticed this issue while running 2.7.4, but the race condition seems to still
> exist in trunk.
