Amar Kamat commented on HADOOP-1839:
------------------------------------
EnumSet<TaskStatus.State> cannot be used since TIP states are different from
task states. Currently there is no concept of TIP state and is computed using
its task states. The TIP state information is made available using the
following APIs
{code}
isCompeted(), isRunning ...
{code}
Hence separate TIP states are required so that some states like PENDING can
also be included.
In TaskInProgress
{code}
enum State {Completed, Running, Killed, Failed, Pending}
{code}
might be the solution over this problem.
> Link-ify the Pending/Running/Complete/Killed tasks/task-attempts on
