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
