I forgot to add to my earlier note, you can also try using Apache Whirr to provision clusters on AWS http://blog.cloudera.com/blog/2012/10/set-up-a-hadoophbase-cluster-on-ec2-in-about-an-hour/

It is likely that Cloudera Manager still has the file open and is writing to it though you have deleted the file itself. Try restarting the service and check if the file is written to $ sudo service cloudera-scm-server restart

The Cloudera Manager and CDH installation can be automated though it would require a bit of programming from your side: Read about Path B installation in this link: http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM5/latest/Cloudera-Manager-Installation-Guide/cm5ig_install_cm_cdh.html Then you can use the Cloudera Manager API to add hosts, services and roles to your cluster http://cloudera.github.io/cm_api/

You had mentioned you want to see the schema, so the describe command is how it is done. If you want to see the entire contents of the table, you can type this on the hbase shell: > scan 'table-name'

Please refer to http://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/HadoopStreaming.html which shows the correct usage. Use -file for each file to be copied across. For example, try: $ /usr/lib/hadoop/bin/hadoop jar /usr/lib/hadoop-mapreduce/hadoop-streaming-2.3.0-cdh5.1.0.jar -file /tmp/mapper.py -file /tmp/reducer.py -mapper /tmp/mapper.py -reducer /tmp/reducer.py -input gutenberg/4300.txt -output output Edit: hyperlink and space char in command

The bottom of the stack trace says "Caused by: java.io.IOException: Cannot run program "/tmp/mapper.py": error=2, No such file or directory". How many nodes are there in this cluster? Have you copied the mapper.py program to all the nodes? It also needs to be executable (chmod 755 mapper.py)

You cannot upgrade just HBase to a newer release. Rather you should wait for the next major or minor release of CDH and upgrade to that. Please subscribe to the announcement forum in this website. Just today CDH 5.1.2 and CM 5.1.2 was released

If you run CM and CDH, CM must be upgraded first because an older CM release cannot manage a newer CDH release. Please upgrade CM as well.
