Lefty Leverenz commented on HIVE-12331:
---------------------------------------
Doc note: This removes *hive.enforce.bucketing* & *hive.enforce.sorting* from
HiveConf.java, and changes the description of *hive.optimize.bucketingsorting*
(created by HIVE-4240 in release 0.11.0 and not documented yet in the wiki) so
Configuration Properties needs to be updated.
* [Configuration Properties -- Query and DDL Execution |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-QueryandDDLExecution]
** [Configuration Properties -- hive.enforce.bucketing |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.enforce.bucketing]
** [Configuration Properties -- hive.enforce.sorting |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.enforce.sorting]
** [Configuration Properties -- hive.optimize.bucketingsorting |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.optimize.bucketingsorting]
(this link will work after the parameter has been documented)
Other wikidocs that need updates because they mention the removed
*hive.enforce.bucketing* parameter:
* [Hive Transactions -- Configuration (annotate *hive.enforce.bucketing* with
version information) |
https://cwiki.apache.org/confluence/display/Hive/Hive+Transactions#HiveTransactions-Configuration]
* [Hive Transactions -- Configuration Values to Set for INSERT, UPDATE, DELETE
(annotate *hive.enforce.bucketing* with version information) |
https://cwiki.apache.org/confluence/display/Hive/Hive+Transactions#HiveTransactions-ConfigurationValuestoSetforINSERT,UPDATE,DELETE]
* [Bucketed Tables (3 instances of *hive.enforce.bucketing*) |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL+BucketedTables]
* [AdminManual Configuration -- Hive Configuration Variables (1 instance of
*hive.enforce.bucketing*) |
https://cwiki.apache.org/confluence/display/Hive/AdminManual+Configuration#AdminManualConfiguration-HiveConfigurationVariables]
* [Configuration Properties -- Transactions and Compactor
(*hive.enforce.bucketing* in list of parameters that need non-default values) |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-TransactionsandCompactor]
