> Project: HBase
> Issue Type: Bug
> Components: Client, master, regionserver
> Affects Versions: 0.98.0, 0.99.0
> Reporter: Nicolas Liochon

>
> Many, but not all, methods in ZKUtil partly hides the interruption: they
> return null or something like that. Many times, this will result in a NPE, or
> something undefined.
> This jira is limited to the getData to keep things small enough (it's used in
> hbase-client code).
> The code is supposed to behave at least 'as well as before', or better
> (hopefully).
> It could be included in a later .98 release (98.1) and in .99
