Lars Hofhansl commented on HBASE-7600:
--------------------------------------
Actually this fix has an interesting side effect.
Sometimes an HBase cluster is wiped by just removing the HDFS data. If the ZK
state stays around we can now no longer create tables for which there exists a
znode already. Before this patch that was possible. So the element of surprised
has increased.
