Description

On a large production cluster, some periodic data processing hangs on FATE transactions. The basic operation is to bulk load the results of a map-reduce job into a temporary table, which is then later deleted. Increasing the number of FATE threads has not improved the situation.

The details are not clear, and unfortunately this system is not online, so I cannot reproduce the logs easily, but they would be huge anyhow.
