Enis Soztutar commented on HADOOP-1839:
---------------------------------------
bq. If we do this how will one fetch reports of all the tasks that are either
completed or pending.
I think of something like
{code}
getTaskReports(String, EnumSet<TaskStatus.State>)
{code}
the last parameter is an set of TaskStatuses used as a filter to select which
TaskStatuses we want. In the JobClient then we may have methods like
getMapTaskReports(), getFailedMapTaskReports(), getSuccessfulMapTaskReports(),
etc.
However i would really like TaskReport to have the state of the task as an
enum, not a string so that we wont have multiconditional string comparison
statements (such as if ("running".equals(state) ).
