>Hi, Sorry if this is not the correct email list. I checked http://ceph.com/help/ but it was blank. My company is trying to evaluate virtualized hdfs clusters using ceph as a drop-in replacement for staging and development following http://ceph.com/docs/master/cephfs/hadoop/. We deploy clusters with ambari 1.3.2. I spun up a 10 node cluster with 3 datanodes, name, secondary, 3 zookeepers, ambari master, and accumulo master. Our process is This was likely the cause of shutdown errors. Should do 1. Run ambari install 2. shut down all ambari services 3. push modified core-site.xml to datanodes, name, secondary 4. restart ambari services I am getting errors /usr/lib/hadoop/bin/hadoop-daemon.sh: Permission denied in the ambari console error log from the command: su - hdfs -c 'export HADOOP_LIBEXEC_DIR=/usr/lib/hadoop/libexec && /usr/lib/hadoop/bin/hadoop-daemon.sh --config /etc/hadoop/conf start datanode' I think this is an ambari issue, but I¹m wondering 1. Is there a detailed guide of using ambari with ceph-hadoop, or has anyone tried it? 2. Is there a script or list of log files useful for debugging ceph issues in general? thanks, kesten ps.
