Hi, We're having problems when trying to deal with the namenode failover, by following the wiki http://wiki.apache.org/hadoop/NameNodeFailover
If we point dfs.name.dir to 2 local directories, it works fine. But, if one of the directories is NFS mounted, we're having these problems: 1) "hadoop dfs -ls" takes 1-2 minutes to finish, and returns error: Bad connection to FS. command aborted. 2) When stop and restart hadoop, Namenode fails to start due to a zombie process. The previous Namenode process became a zombie. We're using hadoop-0.15.3_64. What is the correct way to set this up? Really appreciate your input. Thanks, Nathan
