Summary: Hive2: Query Runtime Prediction: Compact Visual Explain
Plan
Key: AMBARI-19890
URL: https://issues.apache.org/jira/browse/AMBARI-19890
Project: Ambari
Issue Type: Bug
Components: ambari-views
Affects Versions: 2.5.0
Reporter: Pallav Kulshreshtha
Assignee: Pallav Kulshreshtha
Priority: Critical
Fix For: 2.5.0
The explain plan is the key tool DBAs use to optimize queries. Just like full
screen editing is needed for complex queries, it is essential that the explain
plan be compact enough to represent complex queries. The current visual explain
plan only allows a few operators to be displayed at once on the screen.
As a DBA I should be able to see a moderately complex query (~ 15 operators) on
a single screen.
As a DBA the explain plan should focus on the key information, namely
statistics and costs.
As a DBA I should be able to drill down into an operator for additional
information, if needed.
The explain plan should update to reflect changes to tuning parameters.
It should be possible to view the "explain analyze" information in the explain
plan
