Subject [jira] [Commented] (SPARK-6236) Support caching blocks larger than 2G
Date Wed, 16 May 2018 18:25:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-6236?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16477857#comment-16477857
] 

Imran Rashid commented on SPARK-6236:
-------------------------------------

I believe this has actually been solved by other changes, to switch to using ChunkedByteBuffer
etc. *except* for replication.  I plan to address that in SPARK-24296.

I'll leave this open as I do some more testing and get feedback on cases I might have overlooked.
