Subject Re: Connection to HBase seems to hang
Date Fri, 10 Dec 2010 06:49:15 GMT
What J-D was pointing out was that you need the *exact* same hbase and
hadoop jars on *both* client side and server side.

Your client java.class.path shows that you are using apache hadoop 0.20.2
whereas on the server side you are using CDH3 0.20.2+737
These are not compatible and with version mismatches a common symptom is the
client appearing to hang.

So - replace the client hbase & hadoop jars with the exact same jars you are
using on the server side and try again.
