> Currently, if the ZooKeeper process fails, we have little information on why and what happened. This patch addresses this by keeping the last 100 log lines and dumps when the map fails under a RuntimeException.
> Here is an example of a master task failure when there is an invalid JVM argument passed to ZooKeeper. The error is much for obvious now.
