Subject Re: Unable to connect from windows desktop to HBase
Date Mon, 15 Apr 2013 10:41:03 GMT
you need to put  protobuf-java-2.4.1.jar under the hbase_home/lib, then
don't include it in your client class path. but if you used hbase-0.95 or
hbase-0.96.1, protobuf jar is also needed on your client's classpath.
