It seems this is a duplicate of LU-1048, not by pdir ops patch. Sorry.

I just checked the log carefully, and this seems a different problem.

The reason of this failure is that MDT can not be start, which seems related with Liang's pdir patch. I will reassign this to Liang.

Di, since the LU-718 patch will likely not be landed to master for 2.2, since it is more like a feature than a fix at this stage, is it still possible to fix this problem with a smaller patch?

This failure is being hit via autotest:

Will fix it in lu-718

[Di Wang]

This is the error running with my patch. And I will fix it in my patch.
