[jira] [Commented] (MAPREDUCE-4676) Add test for job history cleaner

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13471905#comment-13471905 ] 

Alejandro Abdelnur commented on MAPREDUCE-4676:
-----------------------------------------------

CachedHistoryStorage.getFullJob(jobId) should synchronize on fileInfo from fileInfo.isDeleted() until loadJob(fileInfo) to avoid a race condition.

I'm not very convinced on modifying methods signature for testing purposes only. I'll think about an alternative while you work on the above comment.
