This topic describes how to use Ambari Web features to monitor and manage your HDP Ambari provides an intuitive Web UI as well as a robust REST API, which is particularly useful for automating cluster operations. To do so, Host component resources are usages of a component on a particular host. to a HDFS dir. New services should be added using a Script Action during cluster provisioning. machines. CREATE USER ''@'localhost' IDENTIFIED BY ''; Hosts are top level resources but can also be sub-resources of clusters. Be sure to chmod the script so it is executable by the Agent. secured_url_port=8441. users and groups. This will install an Ambari Metrics Collector into the cluster, and an Ambari Metrics Monitor on each host. You can use Ambari to retrieve this information after the cluster has been created. The Tez View is the primary entry point for finding a Tez job. Command line. It must match storage, using the following instruction: /usr/jdk64/jdk1.7.0_45/bin/keytool -import -trustcacerts -file slapd.crt -keystore For example, using the MySQL database admin utility: # mysql -u root -p At the Group name attribute* prompt, enter the attribute for group name. schema script.
