Subject [jira] Commented: (HADOOP-6162) MapFile doesn't work with serializables other than Writables
Date Mon, 27 Jul 2009 08:17:15 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12735517#action_12735517

Sharad Agarwal commented on HADOOP-6162:

Few comments on the patch:
There are lot of javac warnings. We should get rid of them.
Tests for ArrayFile, BloomMapFile and SetFile also should be added to their respective junit
Should we deprecate constructors takings Writables ?

> Since 0.18 (I think), SequenceFiles have supported serializing arbitrary objects through
the serialization framework.  MapFiles still don't.  They require WritableComparable keys
and Writable values.
