Pig's progress estimation should account for parallel job executions
--------------------------------------------------------------------
Key: PIG-1883
URL: https://issues.apache.org/jira/browse/PIG-1883
Project: Pig
Issue Type: Improvement
Reporter: Laukik Chitnis
Assignee: Laukik Chitnis
Fix For: 0.9.0
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.
