Siddharth Seth updated TEZ-1941:
--------------------------------
Attachment: TEZ-1941.2.txt
The ExecutionContext is supposed to be shared by multiple tasks within a JVM.
Maybe it needs a rename to be more clear. Updated the javadocs for
ExecutionContext.
Since that's per jvm - settting memory in it isn't an option, since it needs to
be task specific.
> Memory provided by *Context.getAvailableMemory needs to be setup explicitly

> *Contexts.getAvailableMemory rely on Runtime..getMaxMemory(). This doesn't
> work for memory scaling if multiple tasks are running within a JVM.
> Container sizes (sent over RPC) can be used for setting up this value.
