Uma Maheswara Rao G commented on HDFS-2720: ------------------------------------------- Thanks a lot,Todd for the suggestions. {quote} For testing on actual clusters, I've done this by shutting down the active NN, then just rsyncing the storage dir to the standby, then starting the standby. {quote} I feel we should automate this once we built the automatic HA right. We were depending on zookeeper to store namespaceID(in our internal HA). But i am not sure how we can handle it in linux HA case. Shall i file one JIRA for it? Thanks Uma > HA : TestStandbyIsHot is failing while copying in_use.lock file from NN1 > nameSpaceDirs to NN2 nameSpaceDirs > ------------------------------------------------------------------------------------------------------------ > > Key: HDFS-2720 > URL: https://issues.apache.org/jira/browse/HDFS-2720 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ha, test > Affects Versions: HA branch (HDFS-1623) > Reporter: Uma Maheswara Rao G > Assignee: Uma Maheswara Rao G > > To maintain the clusterID same , we are copying the namespaceDirs from 1st NN > to other NNs. > While copying this files, in_use.lock file may not allow to copy in all the > OSs since it has aquired the lock on it. -- This message is automatically generated by JIRA.
