> Printing thread dumps when tests fail due to timeouts was introduced in HADOOP-8755, but was enabled in M/R, HDFS and Yarn only. 
> It makes sense to enable in hadoop-common as well. In particular, TestZKFailoverController seems to be one of the most flaky tests in trunk currently and having thread dumps may help debugging this.
