--------------------------------------

Or even better (missed a comma on that first one):

log.debug("zookeeper error reading {}: {}", txpath, ex.toString(), ex);

> 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.
