Subject RE: What does 'TempStatsStore' do ?
Date Tue, 10 May 2011 20:23:49 GMT
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?

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 ?
