> I have a very simple table named 'titles' that I'm playing around with.
> After entering
> 	hql > DELETE * FROM titles;
> I get the following output:
> 08/04/07 15:09:15 INFO hbase.HBaseAdmin: Disabled table titles
> Exception in thread "main" java.lang.NullPointerException
>         at org.apache.hadoop.io.Text.set(Text.java:181)

>         at org.apache.hadoop.hbase.Shell.main(Shell.java:114)
> Every succeeding attempt to query the table results in the following output:
> Exception in thread "main" java.lang.IllegalStateException: region
> offline: titles,,1207564179189

>         at org.apache.hadoop.hbase.Shell.main(Shell.java:114)
> Deleting a specific column on the other hand, as in:
> 	hql> DELETE document:title FROM titles;
> is no problem - I get this output:
> 08/04/07 17:08:02 INFO hbase.HBaseAdmin: Disabled table titles
> 08/04/07 17:08:02 INFO hbase.HBaseAdmin: Enabled table titles
> and everything's all right ever after.
