>                 Key: HBASE-8049
>                 URL: https://issues.apache.org/jira/browse/HBASE-8049
>             Project: HBase
>          Issue Type: Bug
>          Components: regionserver
>    Affects Versions: 0.90.6, 0.94.7, 0.95.0
>         Environment: Including, but not limited to, Centos6_64
>            Reporter: Aleksandr Shulman
>            Priority: Major
>
> Observed Behavior:
> When a user attempts to create a table but there is an issue with the codec, the attempt continues repeatedly. The shell command times out but the RS and Master are both occupied, leading to HBase being down. Further, HBase creates the folders for the table in HDFS.
> The only way to restore the service is by disabling and dropping the table.
> Here are the log lines when a table, t8, is created with this definition:
> create 't8', {NAME=>'f1',COMPRESSION=>'lzo'}
> Error from shell:
> hbase(main):003:0> create 't8', {NAME=>'f1',BLOOMFILTER=>'row', COMPRESSION=>'lzo'}
> ERROR: org.apache.hadoop.hbase.client.RegionOfflineException: Only 0 of 1 regions are online; retries exhausted.
> Log lines on Master (repeats a few times/second):
