Subject [jira] [Commented] (HBASE-12176) WALCellCodec Encoders support for non-KeyValue Cells
Date Tue, 07 Oct 2014 04:25:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12176?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14161452#comment-14161452
] 

Anoop Sam John commented on HBASE-12176:
----------------------------------------

bq. Does it serialize the same way? 
Yes like the old way.
bq. Will this codec have problems reading old files?
Yes.
bq. Should we call this WAL codec something else if there is any danger it does not serialize
in the old KV way?
It do serialize like the old way. Users might be extending this codec and Encoder/Decoder.
 (Phoenix do this) So not able to change the names directly. Leaving it as it is.  

Are you +1 for this patch Stack?

> Now in all Encoder returned by WALCellCodec and SecureWALCellCodec it is assumed that
it will get only KeyValues. If not it just throws IOE. Now we support Cells through out in
write path as well and these Encoders should support non KV cells as well.
