unable to resolve the DNS name
Hello,
I have installed hadoop-hbase cluster (CDH3 distribution).
I am getting following error while trying to connect HBase table using Java
API
11/08/01 20:44:57 ERROR hbase.HServerAddress: Could not resolve the DNS name
of dpev266:60000
Exception in thread "main" java.lang.IllegalArgumentException: Could not
resolve the DNS name of dpev266:60000
at
org.apache.hadoop.hbase.HServerAddress.checkBindAddressCanBeResolved(HServerAddress.java:105)
at org.apache.hadoop.hbase.HServerAddress.<init>(HServerAddress.java:66)

"host dpev266" is working and giving me IP address of the host.
reverse look-up is also working.

There's nothing we can do to help you remotely really... most likely
this is a user error or your OS configuration is different than what
you assume.

Somewhere in your config you're setting a host name as <host>:<port>.
I'm not sure which config that is, but I'd search your config for
"dpev266:60000" and drop the :60000.
