Allen Wittenauer commented on HADOOP-10787:
-------------------------------------------


bq. which means that I can't run a build with bats enabled(even if I skip 
tests).

This is HADOOP-12492 .

bq. GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin14)

So bash on Yosemite.

bq. The root cause seems to the function freetheclasses in 
hadoop_add_common_to_classpath.bats - the unset in that function gives the 
error.

... which is odd, given that same construct is used all over the place.  I'll 
dig a little deeper.

Thanks.
