Subject [jira] [Commented] (MAPREDUCE-5896) Allow InputSplits to indicate which locations have the block cached in memory
Date Tue, 27 May 2014 13:34:02 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14009664#comment-14009664
] 

Tom White commented on MAPREDUCE-5896:
--------------------------------------

@Evolving would mean that it could change incompatibly between 2.4.0 and 2.5.0 say, but not
between 2.4.0 and 2.4.1 - and that might be the right trade off here. Hopefully SplitLocationInfo
would not need to be changed incompatibly, but it's hard to know for sure until it's being
used.
