# For new/unknown/unassigned nodes
default=TX_DC:RAC1
We are mostly done setting up machines. Here are a couple of things to remember:
• Install TaskTracker and DataNode processes on each node in the analytical data
center.
• Do not have a node that has Cassandra running on it and has running services for
TaskTracker and DataNode. Use a separate robust machine to install the master
services such as JobTracker and NameNode.
• Make sure
conf/hadoop-env.sh
has all the JAR files that need to execute
the MapReduce program as a part of the
HADOOP_CLASSPATH
variable.
With all these configurations, your Cassandra cluster should be ready to serve analytical
results to all the concerned people.
