Work Description: fapifta commented on issue #1596: HDDS-2233 - Remove
ByteStringHelper and refactor the code to the place where it used
URL: https://github.com/apache/hadoop/pull/1596#issuecomment-538504664
Acceptance test failures seems to be related to an internally examined
similar failure in XCeiverClientGrpc, where the relevant stack trace is:

From the Integration test failures
org.apache.hadoop.ozone.client.rpc.TestFailureHandlingByClient failure might be
related, but there in the output before the error we can see that the client
wanted replication factor of 3, while the cluster had only 1 DN.
So issues seem to be unrelated, however I can not run these tests locally as
easy as they are timing out in my local machine.
