@Dhruba

In trunk:

{code}
src/main/java/org/apache/hadoop/hbase/HConstants.java:  public static int DEFAULT_HBASE_RPC_TIMEOUT
= 60000;

...

In HConnectionManager.....

      this.rpcTimeout = conf.getInt(
          HConstants.HBASE_RPC_TIMEOUT_KEY,
          HConstants.DEFAULT_HBASE_RPC_TIMEOUT);

> The HBaseRpcServer queues up rpc responses if the socket connection to the client is
not yet ready to receive data. Calls are queued here until a 15 minute timeout occurs. I am
able to generate a full GC when I artificially make a client read rpc-responses very slowly.
This jira is to make this 15 minute time configurable.
