Sergey Soldatov commented on PHOENIX-3721:
------------------------------------------
[[email protected]] At wiki we have suggestion to use $(hbase mapredcp). But
there is an another problem (new one). If we add hbase jars to HADOOP_CLASSPATH
than we need to add phoenix-client as well. Otherwise bulkload will fail with
ClassNotFound. Somehow the classloader is changed in the process and it doesn't
have directory with unpacked jar. I'm trying to figure out when and why it was
changed.

> This is quite strange. I'm using HBase 1.2.4 and current master branch.
> During the running CSV bulk load in the regular way I got the following

> 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?
