[jira] [Commented] (MAPREDUCE-5468) AM recovery does not work for
map only jobs
[ https://issues.apache.org/jira/browse/MAPREDUCE-5468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13744965#comment-13744965 ]
Jason Lowe commented on MAPREDUCE-5468:
---------------------------------------
Are there logs from the AM attempts when this occurred? Last I checked, the AM will recover map tasks if they completed before the AM restarted.
