Subject ./hdfs namenode -bootstrapStandby error
Date Fri, 19 Jul 2013 09:16:55 GMT
I  use hadoop-2.0.5 version and use QJM for HA.


I use ./hdfs namenode -bootstrapStandby for StandbyNameNode, but report
below error:

=====================================================
About to bootstrap Standby ID nn2 from:
           Nameservice ID: mycluster
        Other Namenode ID: nn1

The edit logs are below content in JournalNode:

edits_inprogress_0000000000000016331


The edits_inprogress_0000000000000016331 should contains the 16331-16337
transactions, why the "./hdfs namenode -bootstrapStandby" command report
error? How can I initialize the StandbyNameNode?

Thanks,

LiuLei
