Subject [jira] [Commented] (HIVE-6586) Add new parameters to HiveConf.java after commit HIVE-6037 (also fix typos)
Date Fri, 04 Jul 2014 06:30:35 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14052194#comment-14052194
] 

Lefty Leverenz commented on HIVE-6586:
--------------------------------------

HIVE-4209 added hive.cache.expr.evaluation in 0.12.0, but patch HIVE-6037-0.13.0 truncates
its description to just the first sentence.  The full description should be:

{quote}
If true, the evaluation result of a deterministic expression referenced twice or more will
be cached. For example, in a filter condition like ".. where key + 10 > 10 or key + 10
= 0" the expression "key + 10" will be evaluated/cached once and reused for the following
expression ("key + 10 = 0"). Currently, this is applied only to expressions in select or filter
operators.

> HIVE-6037 puts the definitions of configuration parameters into the HiveConf.java file,
but several recent jiras for release 0.13.0 introduce new parameters that aren't in HiveConf.java
yet and some parameter definitions need to be altered for 0.13.0.  This jira will patch HiveConf.java
after HIVE-6037 gets committed.
> Also, four typos patched in HIVE-6582 need to be fixed in the new HiveConf.java.
