Hello together, after yesterday's success that the queries run now, today, a new chapter has begun in this story. I've borrowed me a second MacBook and now wants to call a second worker into life. Of course, I have read the necessary documentation (http://tajo.apache.org/docs/current/configuration/cluster_setup.html, http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/ClusterSetup.html). In addition I have, however, questions of comprehension.
If I now want to run the cluster it needs to run a HDFS on every node? Correct? I would be interested in how to setup a cluster. How to set up a HDFS for a quick start? How did you set up your cluster? When I look at the necessary configuration I honestly do not clear know what the variables mean and how do I change these entries. <property> <name>tajo.rootdir</name> <value>hdfs://hostname:port/tajo</value> </property> <property> <name>tajo.master.umbilical-rpc.address</name> <value>hostname:26001</value> </property> <property> <name>tajo.master.client-rpc.address</name> <value>hostname:26002</value> </property> <property> <name>tajo.resource-tracker.rpc.address</name> <value>hostname:26003</value> </property> <property> <name>tajo.catalog.client-rpc.address</name> <value>hostname:26005</value> </property> Can you explain me in more details what steps I need to do to link the Macbooks with each other? I would be very grateful if you could assist me on this subject. Best regards, Chris
