> Allow users to customize the Drill log file name
> ------------------------------------------------
>                 Key: DRILL-4986
>                 URL: https://issues.apache.org/jira/browse/DRILL-4986
>             Project: Apache Drill
>          Issue Type: Improvement
>    Affects Versions: 1.8.0
>            Reporter: Paul Rogers
>            Priority: Minor
>             Fix For: 1.9.0
> From John Omernik on the user list:
> I am getting my head around the new Drill config files in 1.8, and I have
> been setting DRILL_LOG_PREFIX in previous versions. Based on what I am
> seeing in drill-config.sh though, it looks like I no longer can set this as
> instead of using a "If set use what's set otherwise default to" methodology
> like other variables, drill-config.sh just exports a static value... is
> this correct?
> My goal is to have logs all in a single directory but have prefixes based
> on the host names... "centralized" logging if you will :)
> Suggestion:
> {code}
> export DRILL_LOG_PREFIX="$DRILL_LOG_DIR/drillbit"
> {code}
> So looking at this, I think that DRILL_LOG_PREFIX is a misnomer, it should
> be DRILL_LOG_PATH = Path to a directory, DRILL_LOG_PREFIX = A prefix to
> prepend to drill log files, thus, in reality, DRILL_LOG_PREFIX should not
> be set to $DRILL_LOG_DIR/drillbit, instead the default should be "
> {code}
> export DRILL_LOG_PREFIX=${DRILL_LOG_PREFIX:-"drillbit"}
> {code}
> and then the next line that makes the drill log path should be:
> {code}
> {code}
> That way the Prefix is just a file prefix, and then in the drill-env.sh I
> could set
> {code}
> export DRILL_LOG_PREFIX="drillbit-$HOSTNAME"
> {code}
> and have all my logs in one folder, but not be overwritten by easy other....
