Subject [jira] Commented: (HADOOP-1839) Link-ify the Pending/Running/Complete/Killed tasks/task-attempts on jobdetails.jsp
Date Mon, 24 Sep 2007 11:01:51 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1839?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12529835
] 

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.

> Ensuring that we can quickly view the Pending/Running/Complete/Killed tasks and task-attempts
from jobdetails.jsp helps to narrow down and hence makes it easier to debug.
