Description
I've been experiencing a case where TabletServers will hold on to many more WAL logs than normal in a (seemingly) unbounded fashion until it is restarted. As a byproduct, it causes extremely long recovery periods after the restart. TabletServers will have hundreds or thousands of WAL entries in ZooKeeper instead of a normal 3-5.
