Description

ContainerPBImpl getId and setId methods can be accessed from multiple threads. In order to avoid any simultaneous accesses and race conditions these methods should be synchronized.

The idea came from the issue described in YARN-10295, however that patch is only applicable to branch-3.2 and 3.1.
