      Description

      Presently, table map information is read directly from zookeeper. This information is pulled using the ZooCache, which adds watches to each table znode, and the name znode. The shell, in particular, pulls table information to provide table names for tab completion.

      It is surprising that clients have watches on znodes for anything but the root tablet and the master's lock/address.
