------------------------------------------------------------------

[~sergey.soldatov], it looks similar to https://issues.apache.org/jira/browse/HBASE-17170.

Workaround till we move to HBase-1.4:-
Include HBase jars also in HADOOP_CLASSPATH if you are running CSVBulkload using "hadoop jar"
command

[~aroberts@fuze.com], see if workaround fix your problem for now.

> Checked the code and it seems that the problem is in the createSysMutexTable function.
Its expect TableExistsException (and skip it), but in my case the exception is wrapped by
RemoteException, so it's not skipped and the init fails. The easy fix is to handle RemoteException
and check that it wraps TableExistsException, but it looks a bit  ugly.  
> [~jamestaylor] [~samarthjain] any thoughts?
