Subject [jira] [Commented] (HADOOP-7298) Add test utility for writing multi-threaded tests

Suresh Srinivas commented on HADOOP-7298:
-----------------------------------------

Todd, given that this is a utility based on which tests are going to be written, can you add
javadoc and possibly examples or brief description on how to use it.

> A lot of our tests spawn off multiple threads in order to check various synchronization
issues, etc. It's often tedious to write these kinds of tests because you have to manually
propagate exceptions back to the main thread, etc.
> In HBase we have developed a testing utility which makes writing these kinds of tests
much easier. I'd like to copy that utility into Hadoop so we can use it here as well.
