------------------------------------

             Summary: DNS not resolving should no longer show in logs as ERROR
                 Key: HBASE-8951
                 URL: https://issues.apache.org/jira/browse/HBASE-8951
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.94.5
            Reporter: Ron Echeverri
            Priority: Minor


Current error message from an hbase-0.94.5 installation:

{{ERROR mapreduce.TableInputFormatBase: Cannot resolve the host name for /192.168.254.178 because of javax.naming.CommunicationException: DNS error [Root exception is java.net.PortUnreachableException: ICMP Port Unreachable]; remaining name '178.254.168.192.in-addr.arpa'}}

According to the Book, "Both forward and reverse DNS resolving must work in versions of HBase previous to 0.92.0."  Given that since 0.92.0, forward/reverse DNS is not required, this should be a WARN and not an ERROR.
