-------------------------------------
Summary: Change Explain ANALYZE to Explain PROFILE
Key: HIVE-23189
URL: https://issues.apache.org/jira/browse/HIVE-23189
Project: Hive
Issue Type: Improvement
Reporter: David Mollitor
Assignee: David Mollitor
{code:none}
EXPLAIN [EXTENDED|CBO|AST|DEPENDENCY|AUTHORIZATION|LOCKS|VECTORIZATION|ANALYZE]
query
{code}
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Explain#LanguageManualExplain-TheANALYZEClause
In Hive, there is an {{EXPLAIN ANALYZE}} query. This can get a bit confusing
because you can run an {{EXPLAIN ANALYZE}} against an {{ANALYZE TABLE}}
statement, so you have something like,...
{code:sql}
EXPLAIN ANALYZE ANALYZE TABLE `myTable` COMPUTE STATISTICS;
{code}
I would like to propose that the name be changed to {{EXPLAIN PROFILE}}. This
borrows from Apache Impala because it has a {{PROFILE}} command which produces
the stats that actually occurred during the query run (much like this Hive
feature).
