Subject [jira] [Commented] (HBASE-7215) Put, Delete, Increment, and Result still implement Writable
Date Wed, 28 Nov 2012 02:58:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13505192#comment-13505192
] 

Lars Hofhansl commented on HBASE-7215:
--------------------------------------

The M/R tests fail because:
# for mapred I forgot to setup the Serilization
# the IdentyReducers still user Writables (and still something else I haven't figured out,
yet).

#2 actually poses an interesting problem. Right now we use Writable as a common super class
to declare the M/R jobs. Now each class we use there needs its own serializer. For example
for Import we'd have to add a serializer for KeyValue (which means KeyValues need to be supported
directly by protobufs).
