What does your /etc/hosts file look like now? You shouldn't remove the 127.0.0.1 line completely - just don't have quickstart or quickstart.cloudera on that line. ... View more

Your original question is answered here: http://community.cloudera.com/t5/Apache-Hadoop-Concepts-and/About-ports-to-write-to-HDFS-in-pseudo-distributed-mode-using/m-p/41456#M2517.   One problem that may explain some of the behavior you're seeing in Spark is that your hosts file has quickstart.cloudera mapped to both 127.0.0.1 and your bridged IP address. quickstart.cloudera should only resolve to the IP address you'll use everywhere - otherwise what you see happening is Spark is looking up the IP for quickstart.cloudera and thinking it's 127.0.0.1 - but that means different machines depending on where it's resolved. ...

Here's a screenshot from my VM if this helps make it clearer what I'm talking about. ... View more

You're looking in HDFS directories - I expect those to be blank unless you've loaded some data to those directories or run some jobs. On the 5.7 VM I just successfully ran some Spark code by typing `pyspark` on the command-line or `spark-shell --master yarn-client` for the Scala shell. I confirmed that the spark-submit and spark-executor commands are also on the PATH. ... View more

Spark is installed in the 5.7 VM. We support Spark-on-YARN, and spark-shell and pyspark are both on the PATH. ... View more

Can you post the output from when you first ran the Sqoop job? It's very unlikely you're hitting the same root problem. If you try it again, be sure you add the --hive-overwrite option since some of the tables & metadata will have already been created. ... View more

Yes it does. ... View more

You are in the home directory, and the $ACCUMULO_HOME warning can be ignored - it only matters if you want to use Accumulo.   The real problem is this:   The number of live datanodes 1 has reached the minimum number 0   It may be as simple as running 'sudo service hadoop-hdfs-datanode restart', and then 'sudo service hadoop-hdfs-datanode status' to check that it's still up after a few seconds. If you continue to have problems, check the logs in /var/log/hadoop-hdfs to see any possible errors. If all else fails, a reboot will restart all the services in the correct order and usually correct any little issues like this. ... View more
