Description

This jira is to clean up few changes done as part of HDFS-8386. As per szetszwo comments, it will affect the write performance. Please see the discussion here

Needs to do the following changes as part of this jira:

1. remove “synchronized" from getStreamer() since it may unnecessarily block the caller
2. remove setStreamer(..) which is currently not used. We may add it in the HDFS-7285 branch and see how to do synchronization correctly.
