> <property> > <name>ceph.root.dir</name> > <value>/mnt/mycephfs</value> > </property> This is probably causing the issue. Is this meant to be a local mount point? The 'ceph.root.dir' property specifies the root directory /inside/ CephFS, and the Hadoop implementation doesn't require a local CephFS mount--it uses a client library to interact with the file system. The default value for this property is "/", so you can probably just remove this from your config file unless your CephFS directory structure is carved up in a special way. > <property> > <name>ceph.conf.file</name> > <value>/hyrax/hadoop-ceph/ceph/ceph.conf</value> > </property> > <property> > <name>ceph.auth.keyfile</name> > <value>/hyrax/hadoop-ceph/ceph/admin.secret</value> > </property> > > <property> > <name>ceph.auth.keyring</name> > <value>/hyrax/hadoop-ceph/ceph/ceph.mon.keyring</value> > </property> These files will need to be available locally on every node Hadoop runs on. I think the error below will occur after these are loaded, so it probably isn't your issue, though I don't recall exactly at which point different configuration files are loaded. > <property> > <name>fs.hdfs.impl</name> > <value>org.apache.hadoop.fs.ceph.CephFileSystem</value> > </property> I don't think this is part of the problem you are seeing, but this 'fs.hdfs.impl' property should probably be removed. We aren't overriding HDFS, just replacing it. > <property> > <name>ceph.mon.address</name> > <value>hyrax1:6789</value> > </property> This was already specified in your 'fs.default.name' property. I don't think that duplicating it is an issue, but I should probably update the documentation to make it clear that the monitor only needs to be listed once. Thanks!
