[jira] [Commented] (HBASE-11407) hbase-client should not require
Jackson for pure HBase queries be executed
[ https://issues.apache.org/jira/browse/HBASE-11407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14041958#comment-14041958 ]
Nicolas Liochon commented on HBASE-11407:
-----------------------------------------
Who is calling this method? We can't just remove it from the client to simplify our dependencies?
If we don't remove it from the pom, or add a specific test, anyone can add the dependency back in any innocent patch (ok, transitive dependencies make this easy to break anyway, but still).
process-wise, we will need the patch for master as well (I've just checked, it contains this toJSON stuff as well...)
The master says
{code}
// TODO make this configurable
// TODO Do we need this anymore now we have protobuffed it all?
{code}
I think we can just remove all this (from the client at least). [~saint.ack@gmail.com], wdyt?

> Including the hbase-client module dependency and excluding Jackson dependencies causes the pure HBase query (run with HTableInterface) fail with Jackson ObjectMapper ClassNotFoundException.
> This is due to org.apache.hadoop.hbase.client.Operation having ObjectMapper statically initialized.
> Moving ObjectMapper to a dedicated utility will help. The patch will be attached.
