TÉLÉCHARGER SANDBOX

En bref

Notes de version

Juin 2018

  • The VirtualBox and VMWare releases of the HDP sandbox had their OS-level packages updated, including a version update to Docker 18.03.0.

  • Image MD5 Checksums:

    • VirtualBox – 533130d23a2f7d919559d0fbb858b09f
    • VMware – 781bd8f2b55660c57e68b90c0af158d3
    • Docker – 5d828411c30c9db0fd663396468e20c6
  • HDP Stack and Ambari: The Sandbox uses the following versions of Ambari and HDP stack. Please use the following release note links provided to view Ambari and HDP stack specific information.

Behavior Changes

  • Les machines virtuelles sont désormais prêtes pour une architecture de données connectée (CDA)
  • Kafka is on by default
  • Builds now include Superset and Druid, both turned off

Known Issues

  • Zeppelin interface on port 9995 may require clearing browser cache on some browsers

Limitations

This is a list of common limitations along with their workarounds.

  • RMP-3586 – Due to dependency of the underlying OS and Virtual machine application, the following may occur when suspending the virtual machine:
    • Region Server service for HBase may be stopped when returning back from suspended state. It will need to be restarted.
    • Ambari Metrics may be stopped when returning back from suspended state since it now uses an embedded HBase.
    • Workaround: Avoid having to suspend your virtual machine.

HDP Services Started Automatically on Startup

When the virtual machine is booted up, the following services are started. If not specified, assume all are java processes. The users that launch the process are the corresponding names of the component. The processes are listed with their main class.

    • DataNode – org.apache.hadoop.hdfs.server.datanode.DataNode
  • Nfs
    • Portmap – Unlike the other processes that are launched by HDFS user, these are run as root user.
    • The nfs process doesn’t show up as a name for jps output
  • HIVE

    • RunJar – metastore – org.apache.hadoop.util.RunJar
    • RunJar – hiveserver2 – org.apache.hadoop.util.RunJar
  • MapReduce
    • JobHistoryServer – org.apache.hadoop.mapreduce.v2.hs.JobHistoryServer

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 Infra
  • 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.
  • Falcon
    • Main – org.apache.falcon.Main
  • HBase
    • HRegionServer – org.apache.hadoop.hbase.regionserver.HRegionServer
    • HMaster – org.apache.hadoop.hbase.master.HMaster
  • Knox
    • gateway.jar – /usr/hdp/current/knox-server/bin/gateway.jar
    • ldap.jar – /usr/hdp/current/knox-server/bin/ldap.jar This process is a mini ldap server
  • Druid
    • org.sparklinedata.druid
  • Superset
  • Storm
    • supervisor – backtype.storm.daemon.supervisor
    • nimbus – backtype.storm.daemon.nimbus
    • logviewer – backtype.storm.daemon.logviewer
    • core – backtype.storm.ui.core
    • drpc – backtype.storm.daemon.drpc

Tous les services HDFS, Druid et Superset sont manquants
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)
