Radim Kolar commented on MAPREDUCE-4275:
----------------------------------------
check for ContainerExecutor.isSetSidAvailable has nothing to do with pstree.
ContainerExecutor needs to be redesigned to make it abstract with almost no
code inside and then create UnixContainerExecuter which will do setsid check
and other unix specific stuff moved there. If linux still needs some special
features then it can subclass unixcontainerexecutor.
