> Yesterday at the Hadoop Summit, the "HADOOP" wireless network was using a
> pair of DNS servers that couldn't resolve {{localhost.}}. This prevented me
> from starting HBase as the construction of the {{HMaster}} was failing with
> the following rather cryptic error:
> {code}
> 2010-06-29 14:30:24,603 ERROR org.apache.hadoop.hbase.master.HMaster: Failed
> to start master

> {code}
> The {{NullPointerException}} in {{getBindAddress}} comes from the following
> line of code:
> {code:java}
> return this.address.getAddress().getHostAddress();
> {code}
> where {{getAddress()}} was returning {{null}}.
> I think the code should check for this case, log an appropriate error message
> (to point whoever is going to troubleshoot the problem in the right
> direction), and throw something else than an NPE.
