Subject [jira] [Commented] (HIVE-6298) Add config flag to turn off fetching partition stats
Date Fri, 24 Jan 2014 01:11:40 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13880587#comment-13880587

Lefty Leverenz commented on HIVE-6298:
--------------------------------------

Please document *hive.stats.fetch.partition.stats* in hive-default.xml.template, then I'll
add it to the wiki for release 0.13.

If you want to be thorough, you can also make these changes to hive-default.xml.template:

* change the default value of *hive.stats.key.prefix.max.length* from 200 to 150 
* document 8 config properties that have been added since release 0.12:
** hive.stats.max.variable.length
** hive.stats.list.num.entries
** hive.stats.map.num.entries
** hive.stats.map.parallelism
** hive.stats.fetch.column.stats
** hive.stats.avg.row.size
** hive.stats.join.factor
** hive.stats.deserialization.factor

These changes were found by comparing files in branch 0.12 & trunk (as of January 13th).
 I've learned my lesson:  from now on I'll check stats patches for new configs.
