  1. The monitor will show you this (like was said in the other answer). connector.instanceOperations().getTabletServers().size() will also provide programmatic access to the number of TServers. See the Connector and InstanceOperations javadoc.

  2. "/accumulo/tables/!0" contains the data for the "accumulo.metadata" (or "!METADATA" if you're using an older version) table.

Use the Accumulo HTTP Monitor page. It can generally be found on port 50095
