Subject [jira] [Commented] (HBASE-11407) hbase-client should not require Jackson for pure HBase queries be executed
Date Tue, 24 Jun 2014 10:36:25 GMT

    [ 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

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 
  // TODO make this configurable
  // TODO Do we need this anymore now we have protobuffed it all?

I think we can just remove all this (from the client at least). [~saint.ack@gmail.com], wdyt?

>             Project: HBase
>          Issue Type: Improvement
>          Components: Client
>    Affects Versions: 0.98.3
>            Reporter: Sergey Beryozkin
>            Priority: Minor
>             Fix For: 0.98.4
>         Attachments: diff.txt
> 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
> Moving ObjectMapper to a dedicated utility will help. The patch will be attached.
