Subject [jira] [Commented] (YARN-4061) [Fault tolerance] Fault tolerant writer for timeline v2
Date Thu, 29 Sep 2016 14:21:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-4061?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15532914#comment-15532914
] 

Joep Rottinghuis commented on YARN-4061:
----------------------------------------

Potential additional challenge, to serialize mutations (in order to spool to a file) we'd
likely use MutationSerialization which is in the org.apache.hadoop.hbase.mapreduce package,
which then contributes to circular dependencies (ATS->HBase->Mapreduce->Yarn) cc
