Chao commented on HIVE-8545:
----------------------------
OK, I managed to find the log file with help from Brock. I think the test
failure is caused by this error:

It seems like a strange error, by looking at the log message I couldn't figure
out why it happened.

> The fix should be easy. However, interestingly, this error doesn't show up
> when the caching is turned off. We need to find out why.
