------------------------------------------------------------
The file in its current state indicates it was an intentional choice not to
redirect stderr. From the [commit
comment|https://github.com/apache/nifi/commit/58cf15a912b5413a4a6e511352b4dac4f7a5dfdd]:
{quote}Pipe stdout to /dev/null and allow stderr to propagate through.
{quote}
I'm happy to submit a change that changes this line include *{{2>&1}}*,
redirecting stderr to stdout, but I'm not sure if that breaks other use cases /
purposes / assumptions about stderr ouput. [~aldrin], can you comment?
----
Update: Looking into the original PR more in depth. It appears the intention
was to optimize for users invoking the script over ssh, to close the stdout
stream but allow stderr to be returned over the ssh tunnel, so that if nifi
bootstrap does not start cleanly, it does not fail silently.
I'm wondering if there is a change that will cause this script to work well for
both use cases?
