Josh Elser commented on ACCUMULO-1472:
--------------------------------------
The {{null/lib/*.jar}} in the {{general.classpaths}} value was bugging me.
Turns out there's another small issue there -- we reference ACCUMULO_HOME from
the current environment, but that value doesn't necessarily exist yet (if it
does, it isn't the right one). When we exec out to the Accumulo processes, that
where we turn the File from the MiniAccumuloConfig into the ACCUMULO_HOME env
variable.

> Key: ACCUMULO-1472
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1472
> Project: Accumulo
> Issue Type: Bug
> Components: mini
> Affects Versions: 1.5.0
> Reporter: Keith Turner
> Assignee: Josh Elser
> Priority: Trivial
> Fix For: 1.5.1, 1.6.0

> I used instamo to run an Accumulo shell against MiniAccumuloCluster. I ran
> the classpath command and noticed it was referencing the hadoop jars from my
> local hadoop install. It was also referencing the hadoop jars from maven.
> I looked at the accumulo-site.xml generated MAC and saw the following :
> {noformat}
> <property><name>general.classpaths</name><value>null/lib/.*.jar,$ZOOKEEPER_HOME/zookeeper[^.].*.jar,$HADOOP_HOME/[^.].*.jar,$HADOOP_HOME/lib/[^.].*.jar,$HADOOP_PREFIX/share/hadoop/common/.*.jar,$HADOOP_PREFIX/share/hadoop/common/lib/.*.jar,$HADOOP_PREFIX/share/hadoop/hdfs/.*.jar,$HADOOP_PREFIX/share/hadoop/mapreduce/.*.jar</value></property>
