Description

Impala seems to be leaking memory in the stress test. I've noticed that the allocated memory has been gradually creeping up. One of the daemons is now sitting at this while no queries are running:

MALLOC: 14364384496 (13698.9 MiB) Bytes in use by application

Whereas it was a couple of gigabytes lower an hour or two ago.
