> Bunch of issues discovered in CachedStore to keep up column statistics:
> 1. The criteria for partition/non-partition is wrong (table.isSetPartitionKeys() is
always true)
> 2. In update(), partition column stats are removed when populate table basic stats
> 3. Dirty flags are true right after prewarm(), so the first update() does not do anything
> 4. Could invoke cacheLock without holding the lock, which results a freeze in update()
