Subject [jira] [Commented] (HBASE-11407) hbase-client should not require Jackson for pure HBase queries be executed
Date Tue, 24 Jun 2014 17:01:32 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14042367#comment-14042367
] 

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

bq. IIRC this is used for the slow operation logging in IPC tracing on the server.
Yeah, I've checked, you're right, toString() is used in a few logs. Not anymore for slowOperation:
the rpcServer uses its own json mapper. But we should not log anyway as it's a security issue
 (iirc it's now correct in the slowOperation and does not expose any potentially private field).

> 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.
