Hello, hopefully I'm doing something wrong here.
1) Tried to start Impala from Manager.
W0524 16:50:49.056499 22241 Client.java:886] Failed to connect to server: quickstart.cloudera/127.0.0.1:8020: try once and fail.
java.net.ConnectException: Connection refused
Name node not running as root cause? Or does the host name look weird?
2) In any case namenode did not (re) start.
[cloudera@quickstart ~]$ sudo -i service hadoop-hdfs-namenode start
Failed to start Hadoop namenode. Return value: 1
3) log4j:ERROR Could not find value for key log4j.appender.RFA
