John Vines resolved ACCUMULO-252.
---------------------------------
Resolution: Fixed
> Improve start-up scripts to avoid common errors
> -----------------------------------------------
>
> Key: ACCUMULO-252
> URL: https://issues.apache.org/jira/browse/ACCUMULO-252
> Project: Accumulo
> Issue Type: Improvement
> Components: start
> Reporter: John Vines
> Assignee: John Vines
> Labels: check, common, error, startup
> Fix For: 1.4.0
>
>
> One of the common issues we have is users not configuration things correctly
> in the accumulo-env.sh script. Rather than default to setting dirs to
> non-existant system variables, we should have a slightly more descriptive
> "/path/to/ITEM". To work nicely with this, we should check these directories
> if they exist, and if not error out with a descriptive message.
> Lastly, we should export all system variables Accumulo will need to read
> (HADOOP_HOME, ZOOKEEPER_HOME, etc.) just in case a user sets the variable but
> doesn't export it.
