Subject [jira] [Commented] (ACCUMULO-1706) Admin Utilities Should Respect EPIPE
Date Sun, 27 Oct 2013 18:17:46 GMT


Mike Drob commented on ACCUMULO-1706:

I'm trying to figure out how to do this with the Shell too, since my common use cases for
automation involve the {{-e}} and {{-f}} flags. However, JLine doesn't expose the underlying
output stream to check for stream closed conditions, and this is further complicated by some
commands optionally outputting to a separate file entirely.

> Many of the admin utilities can potentially print a lot of output, but don't play nice
with standard unix utilities like {{head}}. These tools should periodically check if the stdout
pipe has been closed, and terminate appropriately, instead of continuing to execute and printing
output that nobody will ever see.
> This check can be done using {{System.out.checkError()}}.
