Configuring Hadoop, HBase and Hive Cluster

[Hakan Bo]

Hi,

I am a newbie to Hadoop, HBase and Hive. I installed Hadoop, HBase and Hive in pseudodistributed mode and everything works fine. Now I am planning to set up an simple Hadoop Cluster (5 nodes) with Hive, HBase and ZooKeeper. I´ve read several documentations and instructions before but i could not find a good explanation for my question. I´m not sure, where to run all the daemons. This is my consideration:

Node_1 (Master)
NameNode
JobTrakcer
HBase Master
ZooKeeper (Standalone node; managed by HBase)


Node_2 (Backup_Master)
SecondaryNameNode


Node_3 (Slave1)
DataNode1
TaskTracker1
RegionServer1


Node_4 (Slave2)
DataNode2
TaskTracker2
RegionServer2


Node_5 (Slave3)
DataNode3
TaskTracker3
RegionServer3


I know, in production it is recommended to run ZooKeeper ensemble at an odd number of nodes (seperate Cluster). But for a simple cluster, is it OK to set up a standalone ZooKeeper node which runs on the master node?
Another question is regarding Hive: I know that Hive is a Hadoop client. Should I also install Hive on the master node? Does it make sense?

Thanks for all tips and comments! Hakan

Note: I have just 5 machines to simulate a cluster.

Answering to your second question
You can install hive on master node but you should not
as it is master node, should not use it. It doesn't make sense.
