Subject [jira] [Commented] (HBASE-11762) Record the class name of Codec in WAL header
Date Fri, 15 Aug 2014 21:35:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14099181#comment-14099181

Andrew Purtell commented on HBASE-11762:
----------------------------------------

Patch does not provide support for the encrypting WAL writer nor SecureWALCodec. Please fix,
and consider tests that verify things work as they should for both pairs of WAL readers and
writers (can piggyback on existing tests that check correct handling of the writer class name)

> In follow-up discussion to HBASE-11620, Enis brought up this point:
> Related to this, should not we also write the CellCodec that we use in the WAL header.
Right now, the codec comes from the configuration which means that you cannot read back the
WAL files if you change the codec.
> This JIRA is to implement the above suggestion.
