Tsuyoshi Ozawa updated TEZ-3128:
--------------------------------
Attachment: TEZ-3128.002.patch
Sidd and Hitesh, thank for the clarification.
Created the patch to make the kill faster when shutdown by making the interval
of NMProxy's retry and the timeout of creating connection smaller.
> Avoid stopping containers on the AM shutdown thread

> Project: Apache Tez
> Issue Type: Bug

> During an AM shutdown, the TaskCommunicator is also shutdown and it tries to
> stop containers in the shutdown thread itself. This can cause the AM shutdown
> to block if NMs are not available.
> This likely affects 0.7 as well.
