Whats your goal in terms of dividing this over two nodes? Generally, such division depends on what kind of work load you are running (I am no expert here). So I can easily see moving HBASE_REGIONSERVER and SUPERVISOR to one node so that Storm and HBase work load can use the available resources.
OOTH, if you just want to split the load arbitrarily then I think you can create an arbitrary split while making sure that clients are installed if needed. You can refer to the common-services definitions for dependencies - e.g. https://github.com/apache/ambari/blob/trunk/ambari-server/src/main/resources/common-services/OOZIE/4.0.0.2.0/metainfo.xml -Sumit ________________________________ From: Pratik Gadiya <[email protected]> Sent: Thursday, April 23, 2015 11:11 AM To: [email protected] Subject: Dividing Master Services Hi All, I have deployed 2 node cluster using Ambari ( 1 Master Node and 1 Compute Node). I want to scale this cluster to 2 Master Node and 1 Compute Node. My Services deployed on Master Node are as follows : "components" : [ { "name" : "PIG" }, { "name" : "HISTORYSERVER" }, { "name" : "KAFKA_BROKER" }, { "name" : "HBASE_REGIONSERVER" }, { "name" : "OOZIE_CLIENT" }, { "name" : "HBASE_CLIENT" }, { "name" : "NAMENODE" }, { "name" : "SUPERVISOR" }, { "name" : "FALCON_SERVER" }, { "name" : "HCAT" }, { "name" : "KNOX_GATEWAY" }, { "name" : "SLIDER" }, { "name" : "AMBARI_SERVER" }, { "name" : "APP_TIMELINE_SERVER" }, { "name" : "HDFS_CLIENT" }, { "name" : "HIVE_CLIENT" }, { "name" : "FLUME_HANDLER" }, { "name" : "WEBHCAT_SERVER" }, { "name" : "RESOURCEMANAGER" }, { "name" : "ZOOKEEPER_SERVER" }, { "name" : "ZOOKEEPER_CLIENT" }, { "name" : "STORM_UI_SERVER" }, { "name" : "HBASE_MASTER" }, { "name" : "HIVE_SERVER" }, { "name" : "OOZIE_SERVER" }, { "name" : "FALCON_CLIENT" }, { "name" : "SECONDARY_NAMENODE" }, { "name" : "TEZ_CLIENT" }, { "name" : "HIVE_METASTORE" }, { "name" : "GANGLIA_SERVER" }, { "name" : "SQOOP" }, { "name" : "YARN_CLIENT" }, { "name" : "MAPREDUCE2_CLIENT" }, { "name" : "MYSQL_SERVER" }, { "name" : "GANGLIA_MONITOR" }, { "name" : "DRPC_SERVER" }, { "name" : "NIMBUS" } ], Can someone please let me know how can I divide those services into 2. It would be of great help if someone could actually reply on this mail as follows: Components on Master Node 1: ...., Components on Master Node 2: ..... Reason for dividing as such .... NOTE: I do have same configuration of machines for both the master nodes.
