Lefty Leverenz commented on HIVE-17832:
---------------------------------------
Should the ability to reset
*hive.metastore.disallow.incompatible.col.type.changes* in the metastore be
documented in the wiki?
* [Configuration Properties --
hive.metastore.disallow.incompatible.col.type.changes |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.metastore.disallow.incompatible.col.type.changes]
* [Alter Table -- Change Column Name/Type/Position/Comment |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-ChangeColumnName/Type/Position/Comment]
> Allow hive.metastore.disallow.incompatible.col.type.changes to be changed in
> metastore
