keith-turner opened a new pull request #220: Made scripts print info about failing commands
URL: https://github.com/apache/fluo-uno/pull/220
 
 
   I tried to run Accumulo with JDK 11 using Uno and it failed.  The reason it failed is because the start-yarn.sh script was failing because of [](https://issues.apache.org/jira/browse/HADOOP-15775).  It took me a while to find where the Uno scripts were failing because when the yarn script failed, the uno script just stopped silently.
   
   This change makes the scripts print something like the following when there is a failure.
   
   ```bash
   cat uno/logs/setup/hadoop.out
   Formatting using clusterid: CID-5e5b228b-78e0-4a45-ae29-da9aed51288b
   Starting namenodes on [localhost]
   Starting datanodes
   Starting secondary namenodes [localhost]
   Starting resourcemanager
   Starting nodemanagers
   [ERROR] Error occurred at uno/bin/impl/run/hadoop.sh:29 command: "$HADOOP_HOME"/sbin/start-yarn.sh
   ```
