Andrey Klochkov updated HDFS-3762:

    Attachment: HDFS-3762.patch

Attaching a patch. It's based on junit's run listeners to print thread dumps. I couldn't make
it work until switched from surefire 2.10 to 2.12.

> When a test fails due to timeout it's often not clear what is the root cause. See HDFS-3364
as an example.
> We can print dump of all threads in this case, this may help finding causes.
