*Scenario 1*: Trafodion and Hadoop on all the same nodes. Hadoop Nodes: n0 n1 n2 n3 Trafodion Nodes: n0, n1, n2 n3
Note: Does not matter which node trafodion is installed from ... we almost always install from n0. Best to stay that way (only because we have not tested otherwise... but it should work). *Scenario 2:* Trafodionon a subset of Hadoop nodes Hadoop Nodes: n0, n1, n2. n3 Trafodion Nodes: n2, n3 Note: Trafodion MUST be installed from node n2 (or n3). Trafodion can not be installed today on n0. Note 1: Trafodion may be installed on a subset because n0 and n1 are management nodes. *Scenario 3 (Not supported):* Trafodion and Hadoop on different nodes Hadoop Nodes: n0, n1, n2 Trafodion Nodes (with HBase client): n3, n4, n5 Note: This needs MUCH more testing and I am pretty sure it doesn't works today Note 1: Trafodion will also need to be installed from n3. Future scenarios would include Scenario 3 and Trafodion being able to install outside of the "Trafodion cluster" from one of the Hadoop management nodes (or any node). To be clear, we in no way have this today. -- Thanks, Amanda Moran
