hortonworks ambari

Ambari is the Apache Foundation's Open source project, its advantage lies in the ingenious fusion of existing open source software, to provide cluster automation installation, centralized management, cluster monitoring, alarm and other functions. According to Hortonwork official information, different HDP version, the Ambari version also has different requirements (for example, from the Hortonwork official

How to make Ambari the hive Service in Output Java Dump file1, select "Hive"2, click on the "Configs" tab3, scroll the screen, select "Advanced Hive-env", in the Hive-env template field note the original "Export hadoop_client_opts="-xmx${hadoop_heapsize}m $HADOOP _ Client_opts "Modify the following:#export hadoop_client_opts= "-xmx${hadoop_heapsize}m $HADOOP _client_opts"Export hadoop_client_opts= "-xmx${hadoop_heapsize}m-verbose:gc-xx:+printgcdetails

After you restart the ambari-server, call the install and start APIs, and then return 200. This problem occurs because the server does not receive the heartbeat of the agent after it is started, that is, it does not establish a connection with the agent. At this time, calling the API will only change the status of the cluster service, the actual server does not send commands. For more information about Agent and server connections, go to http:

The agent is a core module of Ambari, which is responsible for executing commands (install/start/stop) and escalation status (Liveness/progress/alert) on the cluster nodes.To understand the implementation details and even modify the source code, first of all to have a general macro understanding. I took a cursory look at the agent code and thought that we could start with three basic abstractions to describe the overall overview.AbstractThe agent defi
