I have Cloudera CDH Quickstart 5.1 running in a VM in my network.
From my local machine I am accessing this VM via spark-shell in yarn-client mode. When I run
sqlContext.sql("show tables").show()a list of my tables are shown, as expected. But when I run
sqlContext.sql("select * from test").show()I got the following error:
sqlContext.sql("select * from test").show()

Caused by: java.net.UnknownHostException: quickstart.cloudera
... 94 moreFrom inside my VM, I can run SELECTs without any problem. I suspect I am missing some configuration. I got my configuration files from Cloudera Manager, acessing Hive > Actions > Download Client Configuration. Extract all files at HADOOP_CONF_DIR and replaced quickstart.cloudera to the actual VM IP using sed.
Any thoughts guys?
