[jira] Created: (PIG-531) Way for explain to show 1 plan at a time
Way for explain to show 1 plan at a time
----------------------------------------
Key: PIG-531
URL: https://issues.apache.org/jira/browse/PIG-531
Project: Pig
Issue Type: Improvement
Reporter: Olga Natkovich
Several users complained that EXPLAIN output is too verbose and is hard to make sense of.
One way to improve the situation is to realize is that EXPLAIN actually contains several plans: logical, physical, backend specific. So we can update EXPLAIN to allow to show a particular plan. For instance
EXPLAIN LOGICAL A;
would show only logical plan.

Olga Natkovich commented on PIG-531:
------------------------------------
Additional suggestion is to compact the output to make it fit on one screen by removing emoty lines, user name , timestamp, etc.

[jira] Updated: (PIG-531) Way for explain to show 1 plan at a time

Viraj Bhat updated PIG-531:
---------------------------
Fix Version/s: 0.5.0
Hi Olga,
I think we have a way to handle it in multi-query optimization. Is it reasonable to close this as fixed.
I see the following in the Multi-query document about explain:
http://wiki.apache.org/pig/PigMultiQueryPerformanceSpecification
explain [-out <path>] [-brief] [-dot] [-param <key>=<value>]* [-param_file <filename>]* [-script <scriptname>] [<handle>]
