keith-turner opened a new issue #957: Fluo scripts copy jars into fluo software 
dir.
URL: https://github.com/apache/fluo/issues/957
 
 
   Currently the fluo script copies jars into `$FLUO_HOME/lib/app/<app name>`.  
This has at least two problems.  First, with concurrency its possible the same 
app name could have different jars over time.  Second, it possible that the 
software directory is not writable. 
   
   One possible fix is the following :
    * Setup `FLUO_TMP` env var in `fluo-env.sh`.  Could default to `/tmp`
    * In scripts copy jars into dir like `mktemp -d 
$FLUO_TMP/fluo-"$app"-XXXXXXXXX`
    * Execute command and after if finishes remove tmp dir
