Description

callTimeoutPool is one of the last things instantiated in PutHiveStreaming.setup(). The cleanup code doesn't check for null before attempting to shutdown the callTimeoutPool, resulting an a NPE if callTimeoutPool is not initialized.

A NPE is also possible while iterating over allWriters.
