multi-threaded hcat client call

I am using hcatalog 0.11 and hadoop 1.2
I have a singleton HCatClient object in my project. I am using that to get a “HCatTable” object so I can find out the
location in HDFS for its files. Works perfectly fine for a single table. For multiple, error…
But I get following error:
org.apache.hcatalog.api.ConnectionFailureException: org.apache.hcatalog.common.HCatException : 9001 : Exception occurred while processing HCat request : TException while adding partition.. Cause : org.apache.thrift.transport.TTransportException: java.net.SocketTimeoutException: Read timed out
Caused by: java.net.SocketTimeoutException: Read timed out
The stack trace is at: http://pastebin.com/4xTXuVvL

I have a test class that demonstrates this behavior: http://pastebin.com/JQF5UDic

What am I missing?

thanks
