Hi ,   I am new to cloudera community.   on : Ubuntu : 12.04   got multiple file permission errors  when i tried to enable HDFS service  from the clouder manager. I believe it would be same for other services.   + exec /opt/cloudera/parcels/CDH-5.3.0-1.cdh5.3.0.p0.30/lib/hadoop-hdfs/bin/hdfs --config /run/cloudera-scm-agent/process/21-hdfs-NAMENODE-format namenode -format -clusterId cluster4 -nonInteractive log4j:ERROR setFile(null,true) call failed. java.io.FileNotFoundException: /var/log/hadoop-hdfs/hdfs-audit.log (No such file or directory) full log : https://drive.google.com/file/d/0B9WOaTjiz-szMkhFLWhGamlZdmc/view?usp=sharing   using single user mode : cloudera-scm   Is there something which I missed to configure. Please suggest.   Thanks     ... View more
