Subject [jira] [Resolved] (ACCUMULO-2078) ACCUMULO_LOG_HOST is incorrectly computed
Date Sat, 21 Dec 2013 00:34:09 GMT


Josh Elser resolved ACCUMULO-2078.

    Resolution: Fixed

Added to the grep that sets ACCUMULO_LOG_HOST so that the example configs (and any user generated
ones) can deal with empty lines or lines with whitespace only.

After verifying that DNS was correctly working for FQDN and hostnames, I dug into how the
remote log host is configured.
> The grep included in all examples will *never* work on a multi-node installation
with the example monitor file. Assuming the user will replace "localhost" with the hostname
of the host running the monitor, this will not work which is extremely misleading.
> The reason is because the grep doesn't exclude any whitespace, so, in o.a.a.s.Accumulo,
the value will be replaced with the hostname for localhost (which will eat all of the logs
intended for the monitor).
