Subject [jira] [Commented] (HBASE-18948) HBase tags are server side only.
Date Thu, 05 Oct 2017 18:19:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18948?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16193368#comment-16193368

Andrew Purtell commented on HBASE-18948:

I think this requires more than a doc update. We should review RPC handling. We allow clients
to build raw cell serializations, potentially including tags, and submit them. I can't say
if they are stripped out or not. It will take a code review to be certain (hint hint). It
is definitely true tags are stripped out when sending RPC responses, except for the replication
client, which uses a special codec that includes tags, so all cell state including tags makes
it to the target cluster. So we also need a point of clarification that custom replication
endpoints (like Lily's indexer) would receive tags. There is a related JIRA about security
enhancements for replication that would be good to take up.
