Subject RE: IOException from HBase Client
Date Mon, 24 Jan 2011 16:55:02 GMT
Sorry, forgot that information

HBase Jar: hbase-0.89.20100924+28.jar
Hadoop Jar: hadoop-core-0.20.2-737.jar

Turns out when I took the hadoop directory out of the classpath it started to work. 

Question: If I want to connect to HBase from a remote client what jars do I need on the client

Thanks again for your help.

Tell us your hadoop version.  Is it 'secure' hadoop (or CDH3b3?).
Looks like a permission issue?  Did you put your cluster's hadoop jar
into hbase/lib?
