For commands that require authentication credentials or JMX credentials, issue the command and
subcommands with only the Cassandra user name and/or secure JMX user name. When a
.dserc file does not exist, you are prompted to enter the passwords on the
next line. For example:
$ dse -u cassandra hadoop fs -ls /prompts you to enter the password to authenticate against the configured Cassandra authentication schema.

Hadoop, hive, mahout, and pig commands must be issued from an analytics node. The hadoop fs options, which DSE Analytics supports with one exception (-moveToLocal), are described in the HDFS File System Shell Guide on the Apache Hadoop web site. DSE Analytics has not yet implemented the -moveToLocal option, but you can use the -copyToLocal.
