Subject [jira] [Commented] (HIVE-5843) Transaction manager for Hive
Date Tue, 25 Feb 2014 20:47:21 GMT

    [ https://issues.apache.org/jira/browse/HIVE-5843?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13912036#comment-13912036
] 

Lefty Leverenz commented on HIVE-5843:
--------------------------------------

HiveConf comment nits:

* hive.compactor.check.interval:  "// Time in seconds between checks to see if any partitions
need compacted."  -->  "need to be compacted."

* hive.txn.timeout:  "// time after which ..."  -->  init cap "Time"

Also a question:  If this goes into Hive 0.13.0, will it be useful immediately or just a piece
of an incomplete feature?  Thirteen new config parameters are added, and I'm wondering about
documentation (as always).  When HIVE-6037 gets committed we won't need to update hive-default.xml.template
anymore but the parameter comments will have to be moved into the definitions.
