Dedicate or Use an Existing Gateway Node
To dedicate or use an existing gateway node (edge node):
Install the storm package on the node:
sudo yum install storm_<version>
For example, for HDP 2.3:
sudo yum install storm_2_3*
HDP 2.2 only: Create a file at
/etc/storm/conf/client_jaas.conf
, and add the following entry to it:StormClient { com.sun.security.auth.module.Krb5LoginModule required useTicketCache=true renewTicket=true serviceName="nimbus" };
Add the following settings to the
/etc/storm/conf/storm.yaml
configuration file.For HDP 2.2:
nimbus.host: <nimbus-host> nimbus.thrift.port: 6667 java.security.auth.login.config: "/etc/storm/conf/client_jaas.conf" storm.thrift.transport: "backtype.storm.security.auth.kerberos.KerberosSaslTransportPlugin"
where
<nimbus-host>
is the host that is running Nimbus. For example:nimbus.host: "c6401.ambari.apache.org"
For HDP 2.3:
nimbus.seeds: <nimbus-host-array> nimbus.thrift.port: 6667 java.security.auth.login.config: "/etc/storm/conf/client_jaas.conf" storm.thrift.transport: "backtype.storm.security.auth.kerberos.KerberosSaslTransportPlugin"
where
<nimbus-host-array>
is an array of hostnames running Nimbus. (The value should come from/etc/storm/conf/storm.yaml
.) For example:nimbus.seeds: ["c6401.ambari.apache.org", "c6402.ambari.apache.org"]
