[jira] [Updated] (MAPREDUCE-6174) Combine common stream code into
parent class for InMemoryMapOutput and OnDiskMapOutput.
[ https://issues.apache.org/jira/browse/MAPREDUCE-6174?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eric Payne updated MAPREDUCE-6174:
----------------------------------
Description:
Per MAPREDUCE-6166, both InMemoryMapOutput and OnDiskMapOutput will be doing similar things with regards to IFile streams.
In order to make it explicit that InMemoryMapOutput and OnDiskMapOutput are different from 3rd-party implementations, this JIRA will make them subclass a common class (see https://issues.apache.org/jira/browse/MAPREDUCE-6166?focusedCommentId=14223368&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14223368)
was:
Once MAPREDUCE-6166 is complete, both InMemoryMapOutput and OnDiskMapOutput will be doing similar things with regards to IFile streams.
In order to make it explicit that InMemoryMapOutput and OnDiskMapOutput are different from 3rd-party implementations, this JIRA will make them subclass a common class (see https://issues.apache.org/jira/browse/MAPREDUCE-6166?focusedCommentId=14223368&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14223368)
