HDP Services Not Started Automatically on Startup

Because of the limited resources available in the sandbox virtual machine environment, the following services are in maintenance mode and will not automatically start. To fully use these services, you must allocate more memory to the sandbox virtual machine. If you want these services to automatically start, turn off maintenance mode. The processes are listed with their main class.

  • Ambari Metrics
  • Atlas
    • Main – org.apache.atlas.Main
  • HDFS
    • SecondaryNameNode – org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode
    • Since on a single node, secondary namenode is not needed, it is not started.

    • HRegionServer – org.apache.hadoop.hbase.regionserver.HRegionServer
    • HMaster – org.apache.hadoop.hbase.master.HMaster
  • Kafka
    • Kafka – kafka.Kafka

missing all services HDFS, Druid, Superset
by Eino Mäkitalo on May 5, 2018 at 2:06 am

These services mentioned in "Services In Maintenance Mode" are not at all there. (I spent several hours with docker version of HDF sandbox to find it out that in Ambari there is no these services) You should NOT download HDF 3.1.0 Sandbox if you are planning to do those tutorials Truck iot etc :-(. People are asking this, but unfortunately you should use HDP only I think. (I think you should have only one package to download)
