Exception after upgrading to 0.20.2
Hello,
After upgrading HBase from 0.20.0 to 0.20.2 I am getting following error
message:
java.lang.reflect.UndeclaredThrowableException

This is happening for the following line in my code:
this.table = new HTable(new HBaseConfiguration(), tableName);
This used to work flawlessly before, so seems like something changed in
HBaseConfiguration, may be? I am looking into this, but any pointers would
be greatly appreciated.
Thanks.

Good thinking, Vaibhav :) I had the old hbase-0.20.0.jar file in my
/hadoop/lib directory. I removed that, added the new one and now it's
working.
Need to figure out a better way to do this. My bad!
Does everyone copy files like this in /hadoop/lib I wonder!
Anyway, thanks for your help.

Are you using 20.2 client?
Please make sure that you use the client with the same version as the
server.
Reagrds,
Vaibhav
