-------------------------------------------------------------
Hadoop_subcommand unit test is failing in Jenkins using ubuntu:xenial . I am unable to reproduce this failure locally in ubuntu:cosmic or ubuntu:xenial. Same unit test has been failing consistently in this issue. I have no idea on why unit test for hadoop_subcommand is failing in Jenkins, [~aw]?

Hadoop_subcommand unit test is failing in Jenkins using ubuntu:xenial . I am unable to reproduce that failure locally in ubuntu:cosmic. Same unit test has been failing consistently in this issue. I can't find the reference from the patch logic to introduce changes to hadoop_subcommand, nor hadoop_subcommand is used in any other place other than the unit test. If the command is not used, can the unit tests be removed, [~aw]?

> The issue is a regression in bash 4.4. See [here|http://savannah.gnu.org/support/?109649]. The extraneous output can break scripts that read the command output.

> {quote}Oh, I think I see the bug. HADOOP_SUBCMD (and equivalents in yarn, hdfs, etc) just needs some special handling when a custom method is being called. For example, there’s no point in checking to see if it should run with privileges, so just skip over that. Probably a few other places too. Relatively easy fix. 2 lines of code, maybe.{quote}
