Subject RE: how to install and distribute master services in 4 nodes.
Date Mon, 07 Apr 2014 08:20:20 GMT
hi Olivier,
With totally 4 nodes(PC), I tried to put all master services into one node. And with all the
4 nodes, tried to put as datanode and installed client as the attached screen.http://postimg.org/image/fflx6tpmz/
In installation, only the 4th node is completely installed. others all have problem. And now
cannot roll back. Seems some client and server cannot running on same node. I tried to re-assign
the master services, but some already blocked and also cannot proceed next any more. Any suggestion,
thank. From: eliyart@hotmail.com

Really appreciate the answers, I am trying to follow it, only the zookeeper need to distribute
into 3 nodes. And for slave and client, beside checking all the nodes with datanode and node
manager, should I also checkbox with the Client or Reginal Server in the web setting.

You can run all master services on a single node or if was you I will run the datanode / nodemananger
on every nodes. 
Kind regards

Trying to install hadoop by horton, there some many master services, such as HDFS, Yarn+mapreduce,
Nagios, Ganglia, Hive, Hbase and Pig as the image below.

Currently, only have 4 nodes, and as below, 3 nodes may ocuppy by master services, and only
1 node left for datanode.

Does all the master services neccessary.  After searching, seem all neccessary. Can all the
master services put into one node, if they are not cost much resources. Or even master services
are distrbuted for 3 nodes, I still can distribute data services into 3 or 4 nodes.

Any suggestion, thanks.
