I have a new candidate branch. It appears the issue with the impersonation tests was that we creating an excessive number of UserGroupInformation objects. That then caused an excessive number of FileSystem objects to be created. I have a patch up for DRILL-4065 that seems to resolve the issue. Running the test suites now against my commit here: https://github.com/jacques-n/drill/tree/drill-1.3.0
If the test looks good, I'll roll another release. -- Jacques Nadeau CTO and Co-Founder, Dremio On Tue, Nov 10, 2015 at 9:33 AM, Jinfeng Ni <[email protected]> wrote: > I run the impersonation test through IntelliJ and kept looking at the > thread # through Activity Monitor.
