Lengthen hbase RPC timeout for local test environment
Lengthen hbase RPC timeout for local test environment

The previous value of 3000ms seems to have been too short for our local
test environment, causing HBase table loading errors and other odd results.
This change bumps up the timeout a bit, but otherwise keeps things the
same.
