I have installed Hadoop using Cloudera Manager on 8 VMs in Google Computing
I have several doubts regarding this installation.
Is it true that the manager will install Hadoop on all 8 VMs?
I wanted to test the installation so while I was searching for some
examples, I found the quick start guide in
https://ccp.cloudera.com/display/CDH4DOC/CDH4+Documentation. I wanted to
use the example given in page 13. However, I'm not able to run from that
step. I had to install "hadoop-0.20-conf-pseudo". I'm not sure as to why I
have to install Hadoop again.
When I followed, I could start Hadoop but again stuck in starting
MapReduce. It throws an error saying "Error: JAVA_HOME is not set and Java
could not be found". However, java is installed and echo $JAVA_HOME is
giving a path.
Please tell me as to what is happening and how do I test Hadoop
installation. I have only one more week of GCE access and need to run an
application before that.
