Subject Table exist and not exist at the same time.
Date Thu, 05 Jul 2012 11:06:10 GMT
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
