Yammer Dropwizard and Kerberos

[Alex Kozlov <al...@gmail.com>]

I am having problems using Yammer Dropwizard (http://dropwizard.io/) with
secure (Kerberos) connection to HBase: whenever I put the dropwizard jar on
the classpath the HBase connection fails.

One the client:

*DEBUG [2015-01-14 00:29:35,765]

On the server:

*RpcServer.listener,port=60000: count of bytes read: 0*
*org.apache.hadoop.hbase.security.AccessDeniedException: Authentication is

The weird thing is that the same code works w/o the jar on the classpath.
It appears something in the dropwizard code static initialization is
breaking Kerberos authentication.  Has anyone seen this problem before?

Thanks,
