---------------------------------------
Hi,
I am using hbase-0.94.8.jar and getting the following exception while
trying to connect -
WARN client.HConnectionManager: Error obtaining current user, skipping
username in HConnectionKey
java.io.IOException: failure to login

What is the solution to this problem?
I have embedded this hbase jar in an osgi bundle and am unable to
connect to my HBase database.
Thanks in advance for any help.

> Sometimes, some non-IOException prevents User.getCurrent() to get a username.
> It makes it impossible to create a HConnection. We should catch all
> exception here:
> {noformat}
> try {
> User currentUser = User.getCurrent();
> if (currentUser != null) {
> username = currentUser.getName();
> }
> } catch (IOException ioe) {
> LOG.warn("Error obtaining current user, skipping username in
> HConnectionKey",
> ioe);
> }
> {noformat}
> Not just IOException, so that client can move forward.
