> The current syntax is:
> {noformat}
> --scratch_dirs=/data/1/impala/impalad,/data/10/impala/impalad,/data/11/impala/impalad,/data/2/impala/impalad,/data/3/impala/impalad,/data/4/impala/impalad,/data/5/impala/impalad,/data/6/impala/impalad,/data/7/impala/impalad,/data/8/impala/impalad,/data/9/impala/impalad,/data/12/impala/impalad
> {noformat}
> The current syntax for the data cache is
> {noformat}
> --data_cache_dir=/tmp --data_cache_size=500MB
> {noformat}
> One idea is to allow optionally specifying the limit after each directory:
> {noformat}
> --scratch_dirs=/data/1/impala/impalad:500MB,/data/10/impala/impalad:2GB,/data/11/impala/impalad
> {noformat}
