Thanks for all the help, guys! Let me give back to community by listing all the minimal steps I needed to make it work on current versions of the software. Ubuntu 12.04.2 LTS ceph 0.61.2-1precise Hadoop 1.1.2 1. Install additional packages: libcephfs-java libcephfs-jni 2. Download http://ceph.com/download/hadoop-cephfs.jar 3. In hadoop-env.sh export HADOOP_CLASSPATH=/path/to/hadoop-cephfs.jar:/usr/share/java/libcephfs.jar export HADOOP_OPTS="-Djava.net.preferIPv4Stack=true" 4. Symink JNI library cd $HADOOP_HOME/lib/native/Linux-amd64-64 (or Linux-i386-32 on 32-bit platform) ln -s /usr/lib/jni/libcephfs_jni.so . I have tried adding -Djava.library.path=/usr/lib/jni to HADOOP_OPTS in hadoop-env.sh and exporting LD_LIBRARY_PATH=/usr/lib/jni in hadoop-env.sh, but it didn't work for me. I'd love to hear about a more elegant method of making Hadoop Ceph JNI aware w/o symlinking. 5. core-site.xml needed all 3 properties below fs.default.name=ceph:/// fs.ceph.impl=org.apache.hadoop.fs.ceph.CephFileSystem ceph.conf.file=/etc/ceph/ceph.conf Cheers, Ilja This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
