Is there some advantage to gathering stats in this case?
Thank you,

Thanks, I found some new configure options for hive.stats, I'll change them.

TempStatsStore is a derby database for stats gathering (intermediate stats). You can turn off stats gathering by set hive.stats.autogather=false.

I don't know what TempStatsStore is, but derby.log is an artifact of using the default metastore db, derby. I was unable to figure out a way to get derby.log to not be created or to be created in a particular directory. I also never saw anything useful in that file. I delete it whenever I see it.
What's in TempStatsStore?

hi,
After upgrade to hive 0.7, I found there will a file named 'derby.log' and directory named 'TempStatsStore' be created every time I run the hive job . What does these files do? Is there a way to prevent them created ?
