Navis commented on HIVE-6229:
-----------------------------
"hive.stats.key.prefix" is the key for JobConf instance used only for partial
scan command. I think the name of config is a little misleading. (It's not
related with other two similar-named configurations)
> Stats are missing sometimes (regression from HIVE-5936)
