Subject [jira] Commented: (HADOOP-2733) Compiler warnings in TestClusterMapReduceTestCase and TestJobStatusPersistency
Date Sun, 10 Feb 2008 00:24:11 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12567385#action_12567385
] 

Chris Douglas commented on HADOOP-2733:
---------------------------------------

Instead of modifying EchoMap and EchoReduce, can they be removed in favor of o.a.h.mapred.lib.IdentityMapper
and o.a.h.mapred.lib.IdentityReducer?
