Subject [Thrift server] java.lang.NullPointerException
Date Tue, 01 Sep 2009 16:40:26 GMT
Hi,

I hope it'll be the right list to send such issue but I just managed to
get the following exception with the thrift server for HBase 0.20RC2 (as
found a week or so via [1]):

2009-09-01 16:28:14,655 INFO org.apache.zookeeper.ClientCnxn: Server

I've been able to use this setup quite well until now so I'm not sure how
to interpret it but I thought someone might be interested.

I'm using the Python thrift bindings on the client side.
