Question

I am facing a weird problem. I was accessing my HBase tables through an API. Midway during execution I got a RegionNotServing for my table ‘x’. But My HRegionServers were working fine.

When I tried to list the tables from HBase Shell I could not find my table ‘x’. When I tried to Disable my table ‘x’ it threw a TableNotEnabledException and when I tried to Enable my table ‘x’ it threw me a TableNotDisabledException.

Attached is the Exeption I got:

hbase(main):002:0> disable 'x'

ERROR: org.apache.hadoop.hbase.TableNotEnabledException: org.apache.hadoop.hbase.TableNotEnabledException: x

        at org.apache.hadoop.hbase.ipc.HBaseServer$Handler.run(HBaseServer.java:1336)

Here is some help for this command:
Start disable of named table: e.g. "hbase> disable 't1'"


hbase(main):003:0> enable 'x'

hbase(main):004:0>

I had a similar issue before. The problem was because Zookeeper was holding the table.
So I deleted the table manually by following the below steps

1. Enter into hbase zookeper client mode using hbase zkcli command
2. Delete the table using the command delete /hbase/table/x
