Table exist and not exist at the same time.
Hi,
Yesterday I stopped my cluster because of a storm. It did not went up
well so I have formated the hadoop FS and restarted it.
Now, when I'm trying to re-create my schema, I'm facing some issues.
It's telling me that the table don't exist when I want to delete it,
but that the table exist when I try to create it.
Here is the simple code.
HBaseAdmin admin = new HBaseAdmin(config);
if (admin.tableExists(Constants.TABLE_WORK))
{
admin.disableTable(Constants.TABLE_WORK);
admin.deleteTable(Constants.TABLE_WORK);
}
admin.createTable(table_work);
admin.close();
tableExists return true. But createTable return the expection below.
I have done a rm -rf on the hadoop storage directory and formated the
namenode. So what did I missed? If I try to put some data into this
table I get org.apache.hadoop.hbase.TableNotFoundException: Cannot
find row in .META. for table: work, row=work,,99999999999999 but if I
look at the web interface, there is no table anywhere except META and
ROOT.
Do you have any idea where I should look at?
Thanks,
JM

Super, thanks.
Seems that everything is now working fine after I removed the entries.
I have formated my HDFS because of this issue ;) Next time I will wait
a bit before doing that.
Thanks,

Hi JM,
You can simply remove the znode's if you like, that ought to do it.

Hi Lars,
For for pointing me to the right direction.
I have already restarted ZK but I did not removed anything on its server.
Here is the output of the ZK ls. There is few tables I already removed
(test3, work, etc.)...
[zk: cube(CONNECTED) 8] ls /hbase/table
[work, work_sent, .META., -ROOT-, work_proposed, test3]
I removed the table using rmr /hbase/table/work is that safe? Or am I
still better to restart everything?

Hi JM,
So you already wiped everything on the HDFS level? The only thing left is ZooKeeper. It should not hold you back, but it could be having an entry in /hbase/table? Could you try the ZK shell and do an ls on that znode?
If at all, if you wipe HDFS anyways, please also try wiping the ZK data and try again.
