Subject [jira] [Commented] (HBASE-12441) Export and CopyTable need to be able to keep tags/labels in cells
Date Fri, 07 Nov 2014 05:27:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14201619#comment-14201619

Anoop Sam John commented on HBASE-12441:
----------------------------------------

Why default the Codec which RPC uses is KeyValueCodec which strips tags
There is a KeyValueCodecWithTags you can see. This will carry the tags also.
Replication uses this.
To carry tags from server to client, this Codec should be used at both ends.

> Export and CopyTable (and possibly other MR tools) currently do not carry over tags/labels
in cells.
> These tools should be able to keep tags/labels in cells when they back up the table cells.
