----------------------------------

Hi Izaak,

Thanks for responding.  then the trouble could be in the way im making the table.
If you could, please test creating the table using HTableDescriptor.

		log.info("creating table in HBase: tableA");
		HTableDescriptor desc = new HTableDescriptor("tableA");

		desc.addFamily(new HColumnDescriptor("label:"));
		HBaseAdmin admin = new HBaseAdmin(hbaseConf);
		if (!admin.tableExists(new Text("tableA"))) {
			try {
				admin.disableTable(desc.getName());
				admin.deleteTable(desc.getName());
			} catch (TableNotFoundException te) {
				log.info("no existing table was found to delete.");
			}
			admin.createTable(desc);
			for (HTableDescriptor table : admin.listTables()) {
				log.info("found table: " + table.getName());
			}
		}

>    Affects Versions: 0.2.0

> Process:
> One the 1st MR job, i use tableExists( new Text("TestTable5")) & tableCreate to create
the table.
> On the 2nd MR job, I call tableExists(new Text("TestTable5")), which returns false, then
i call disableTable, deleteTable, and finally createTable.
> Workaround for now is to avoid using Text.   tableExists(byte[]) works when i tested
it.
