Sergey Beryozkin commented on HBASE-11407:
------------------------------------------

Sure, I'd be up for it. But I can see Operation.toString() documentation says 
that a JSON representation is created by default so I'm not sure how sensitive 
would it be to remove the dependency.


> hbase-client should not require Jackson for pure HBase queries be executed

> 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.
