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.
{quote}
> Add new parameters to HiveConf.java after commit HIVE-6037 (also fix typos)

> Key: HIVE-6586
> URL: https://issues.apache.org/jira/browse/HIVE-6586
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.13.0
> Reporter: Lefty Leverenz
> Labels: TODOC14
>
> 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.
