Izaak Rubin commented on HBASE-777:
-----------------------------------
I think this might be the problem: under the hood, all String/Text objects are
converted to byte[]. For Text, the Text.getBytes() method is used, which can
sometimes pad on extra '\0' characters at the end of the array. I looked into
it, and in the case of Text("RelatedAlbums") there is a single extra '\0'
character that you would not get in Bytes.toBytes("RelatedAlbums"). My guess
is that when you create the table in the new shell, the name doesn't have any
padding '\0's.
Another thing I should mention is that Text is slowly being faded out of HBase
completely. 0.2 is still backwards-compatible and will handle Text arguments,
but the plan for 0.3 is that Text will disappear entirely.
Try using String instead of Text and let me know if that fixes the problem.
I've seen a number of issues stemming from the '\0' padding in Text - if this
is indeed the problem here, I think I'll make an issue to fix 0.2 so that Text
works exactly the same as String (takes care of '\0' trimming).

> URL: https://issues.apache.org/jira/browse/HBASE-777
> Project: Hadoop HBase
> Issue Type: Bug
> Components: client
> Affects Versions: 0.2.0
> Reporter: Todd Lipcon
> Priority: Minor
>
> Using the old shell I was able to use CREATE TABLE to create a table named
> 'RelatedAlbums' and then access it from Java using new HTable(conf, new
> Text("RelatedAlbums")).
> Using the new shell, trying to use 'create' from the irb shell and then that
> same constructor results in the table not being found.
