Subject [jira] [Commented] (HBASE-11407) hbase-client should not require Jackson for pure HBase queries be executed
Date Tue, 24 Jun 2014 11:56:24 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14042013#comment-14042013

Nicolas Liochon commented on HBASE-11407:
-----------------------------------------

Yeah that's what I prefer. Except if it's actually used somewhere then yes we have to pay
the cost, but the extra dependency in the hbase client does not justify it.  We should not
workaround our dependencies (I do understand that you don't care much as you have an immediate
issue to solve, but on the long term it's better for all of us). I'm +1 for your patch if
we remove the dep in the master.

> 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.
