Hi Huang,
Few things.
1), cdh3.4 is a pretty old version. You should thing about upgrading
to a more recent version.
2) Have you checked you hosts files? Can you ping CH35 (if it's your
host name) from you ZK and other servers?

Can you update your CDH and hbase?
This seems pretty basic dns setup issue:
13/07/03 11:22:36 ERROR hbase.HServerAddress: Could not resolve the DNS
name of CH35
java.lang.IllegalArgumentException: hostname can't be null
Can you fix this first?
