---------------------------------------------------------------
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. Also, the revised description of configuration property
*hive.stats.gather.num.threads* needs to be documented with release information.
* [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]
* [Configuration Properties -- hive.stats.gather.num.threads |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.stats.gather.num.threads]
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.)
