Re: Help on running JUnit test cases on Hadoop-Common-trunk

Elizabeth,

 Welcome to Apache Hadoop!

 This seems like we either have broken or flaky tests (TestZKFailoverController).

 Looks like you are already engaged on HADOOP-9745. If you are feeling adventurous, we'd love to get your help in fixing them too.

thanks,
Arun
