I set up a hbase cluster to store data from opentsdb. Recently due to reboot of some of the nodes, hbase lost the table \"tsdb\". I can still it on hbase\'s master node page
To expand on @Devin Bayer's answer, run:
delete /hbase/table/
if you find any zombie tables being maintained by the zookeeper. For more help on this issue, you should google 'HBase zombie tables'.
