Subject [jira] [Commented] (HIVE-10343) CBO (Calcite Return Path): Parameterize algorithm cost model
Date Thu, 16 Apr 2015 02:18:58 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14497467#comment-14497467
] 

Lefty Leverenz commented on HIVE-10343:
---------------------------------------

Doc note:  I added two labels (TODOC-CBO and TODOC1.2) because commit r1673948 went to the
cbo branch but this jira is marked with Fix Version 1.2.0.

The patch adds seven configuration parameters to HiveConf.java, so they need to be documented
in the wiki for release 1.2.0 or whenever the cbo branch gets merged to trunk.  Another parameter
is removed (*hive.cbo.costmodel.extended* which came from HIVE-10040).

* hive.cbo.costmodel.extended
* hive.cbo.costmodel.cpu
* hive.cbo.costmodel.network
* hive.cbo.costmodel.local.fs.write
* hive.cbo.costmodel.local.fs.read
* hive.cbo.costmodel.hdfs.write
* hive.cbo.costmodel.hdfs.read
