Ted , I appreciate your help！ I have read HBASE-2502 and mail of "hbase with multiple interfaces"
I rent the cluster to test HBase, so i can't modify the hardware configuration. (Maybe others need the dual NICs) Can I temporary modify some code to fix the issue? (e.g. Replace the process that look up IP address in DNS with some hardcode(fixed IP address) ) Anybody can give me some clues? 2010-11-04 Pan.W 发件人： Ted Yu 发送时间： 2010-11-04 17:37:56 收件人： user 抄送： 主题： Re: HBase failure causes dual NIC ? See https://issues.apache.org/jira/browse/HBASE-2502 Deactivate one of the dual NICs.
