hbase cannot find an existing table

Question

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

Answer 1

More instructions on deleting the tables:

~/hbase-0.94.12/bin/hbase shell

> truncate 'tsdb'
> truncate 'tsdb-meta'
> truncate 'tsdb-uid'
> truncate 'tsdb-tree'
> exit

I also had to restart the tsd daemon.

Answer 2

I do face these issues at my workplace. I usually either delete the znodes and them remove the corresponding table or restart hbase both HMaster and Hregionserver to get hbck status OK.

Answer 3

try to fix meta

1. hbase hbck
2. hbase hbck -fixMeta
3. hbase hbck -fixAssignments
4. hbase hbck -fixReferenceFiles

after and try again

Answer 4

I get a similar error message when I try an HBase connection from a Java client on a machine that doesn't have the TCP privilege to access the HBase machines. The table indeed exists when I do hbase shell on the HBase machine itself.

Does opentsdb has all the privileges/port config to access the HBase machine ?
