[cdh-user] Re: RuntimeException running the hdfs command (core-site.xml not found)

I had the same problem.  When I try 'hadoop fs -ls /', the java runtime error occurs 'cannot find core-site.xml'.  Yet I could access the hdfs via text browser elinks.

Weirdly enough a restart of the machine the next day solved the issue. I was playing around with hadoop and spark classpaths mainly for slf4j purposes and I'm guessing some link change messed up the hadoop configuration.  It returned back to normal now, everything running 'smoothly'.

Yes, I checked /etc/hadoop/conf/ configuration. 

Directory contains container-executor.cfg, core-site.xml, hadoop-env.sh, hdfs-site.xml, log4j.properties, mapred-site.xml, and taskcontroller.cfg configuration files.

In core-site.xml contains correct path for HDFS:

<property>

    <name>fs.defaultFS</name>

    <value>hdfs://------:8020</value>

  </property>

I have deployed the client configuration also from CM UI but still same error.

Can you please check if your /etc/hadoop/conf/ carries all cluster
configs, with proper contents? If not, can you perform a Deploy Client
Configuration from the CM UI?
