Lefty Leverenz commented on HIVE-6229:
--------------------------------------
This adds hive.stats.key.prefix.reserve.length to HiveConf.java and
hive-default.xml.template.
I can document it in the wiki (for Hive 0.13.0) along with
hive.stats.key.prefix.max.length, but hive.stats.key.prefix has an "internal
usage only" comment so are these other two hive.stats.key.prefix.* config
params also internal use only?
> Stats are missing sometimes (regression from HIVE-5936)
