Re: Hadoop over Lustre?

[Owen O'Malley]

Check the setting for mapred.system.dir. This needs to be a path that is on
a distributed file system. In old versions of Hadoop, it had to be on the
default file system, but that is no longer true. In recent versions, the
system dir only needs to be configured on the JobTracker and it is passed to
the TaskTrackers and clients.
