Bill Graham created PIG-2871:
--------------------------------
Summary: Refactor signature for PigReducerEstimator
Key: PIG-2871
URL: https://issues.apache.org/jira/browse/PIG-2871
Project: Pig
Issue Type: Bug
Reporter: Bill Graham
Assignee: Bill Graham
The signature to this method should be refactored to provide more context so
the implementer has access to the map and reduce plans. Also passing both
{{Job}} and {{Configuration}} is redundant, since the latter can be obtained by
the former.
I propose changing this:
{noformat}
int estimateNumberOfReducers(Configuration conf, List<POLoad> lds, Job job)
throws IOException;
{noformat}
To this:
{noformat}
int estimateNumberOfReducers(Job job, List<POLoad> lds, MapReduceOper
mapReduceOper) throws IOException;
{noformat}
This interface is evolving and hasn't yet been released so this is safe.
