Thejas M Nair updated PIG-1883:
-------------------------------
Release Note:
The progress estimation based on critical path is used to log progress when the
property pig.paratimer is set to "true". If it is set to "both", then both old
and new progress indicator algorithms are used.
The paratimer is based on ideas proposed in
http://www.cs.washington.edu/homes/kmorton/camera-ready.pdf .
> Pig's progress estimation should account for parallel job executions

> Currently, Pig's progress estimation is based on the percentage of jobs
> completed out of the total number of MR jobs. However, since the MR operators
> are arranged in a DAG (and hence more than 1 job might be submitted for
> execution in parallel), the progress estimation can be improved by
> considering the number of jobs in the critical path, instead of just the
> total number of jobs.
