I am using an osgi bundle AAA in which I have embedded the
hbase-0.94.8.jar and hadoop-core-1.0.4.jar.
I see that the hbase-0.94.8.jar does contain the class
org.apache.hadoop.hbase.ipc.WritableRpcEngine.
I have added this bundle AAA as a dependency in my client maven project
bundle XXX.
Rgds,
Yogesh

> Sometimes, some non-IOException prevents User.getCurrent() to get a username.
> It makes it impossible to create a HConnection. We should catch all

> Not just IOException, so that client can move forward.
