Can you try turning on client debugging? In your Hadoop configuration file core-site.xml:
<property>
<name>fs.ceph.commandLine</name>
<value> --debug_client 20 --debug_ms 20</value>
</property>

Where was the failure exactly? I suspect that the failure is occurring when ceph_mount(..) is being called.
