Lefty Leverenz commented on HIVE-17652:
---------------------------------------
Doc note: This removes the syntax ALTER TABLE ... COMPUTE STATISTICS
PARTIALSCAN, which was introduced in release 0.11.0 by HIVE-3958. The syntax
still needs to be documented in the Statistics wikidoc, and the removal of
reserved keyword PARTIALSCAN needs to be listed for release 3.0.0 in the DDL
doc.
* [Statistics -- ExistingTables–ANALYZE |
https://cwiki.apache.org/confluence/display/Hive/StatsDev#StatsDev-ExistingTables–ANALYZE]
* [DDL -- Reserved Keywords |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-ReservedKeywords]
Added a TODOC3.0 label. (Please add your own TODOC labels and doc notes from
now on. I no longer monitor Hive email for doc issues.)
