   * See the [[http://wiki.apache.org/hadoop/ZooKeeper/Troubleshooting ZooKeeper Operating
Environment Troubleshooting]] page.  It has suggestions and tools for checking disk and networking
performance; i.e. the operating environment your zookeeper and hbase are running in.  ZooKeeper
is the cluster's "canary".  It'll be the first to notice issues if any so making sure its
happy is the short-cut to a humming cluster.

+ Enable/Disable of a table doesn't work reliably
+ == Causes ==
+ == Resolution ==
+ This is a known issue.  Will be fixed in hbase 0.21 (BigTable is not like a RDBMS -- You
shouldn't need transient temporary tables... though they can be useful testing)
