Description

When using speculative execution, web interface can show inconsistent numbers and status.

E.g. both speculative executed tasks as SUCCEEDED in taskDetails.jsp:

Task Attempts Machine Status Progress Start Time Finish Time Errors Task Logs Counters
task_0005_m_000246_0 fwm521057.inktomisearch.com SUCCEEDED 100.00% 6-Jul-2007 18:27:10 6-Jul-2007 18:31:36 (4mins, 26sec)
task_0005_m_000246_1 fwm521107.inktomisearch.com SUCCEEDED 100.00% 6-Jul-2007 18:28:07 6-Jul-2007 18:32:10 (4mins, 3sec)

or in jobDetails.jsp the number of completed tasks does not match the total number of tasks even after the job has finished.
