  • Accessing your Cluster 7/6/2012© 2012 MapR Technologies Accessing your Cluster 1
  • Accessing your Cluster Agenda • Administrative Access: the MapR Control System (MCS) • Exercise: The MCS • The MapR Client • Exercise: The MapR Client • Direct Access NFS • Exercise: NFS • The Hive ODBC Connector© 2012 MapR Technologies Accessing your Cluster 2
  • Accessing your Cluster Objectives At the end of this module you will be able to: • Manage your cluster with the MapR Control System • Copy files to and from your cluster via NFS • Use the MapR Client to access your cluster • Explain the steps involved in using the Hive ODBC Connector with a BI application© 2012 MapR Technologies Accessing your Cluster 3
  • The MapR Control System© 2012 MapR Technologies Accessing your Cluster 4
  • The MapR Control System  https://<web_server>:8443  Can manage multiple clusters – Defined in mapr-clusters.conf  Standard set of tools to manage cluster© 2012 MapR Technologies Accessing your Cluster 5
  • Instructor Demo: The MCS© 2012 MapR Technologies Accessing your Cluster 6
  • Exercise: The MCS  Connect to the MCS with a browser  Navigate to the Dashboard, Nodes, Volumes, JobTracker and other pages© 2012 MapR Technologies Accessing your Cluster 7
  • The MapR Client© 2012 MapR Technologies Accessing your Cluster 8
  • The MapR Client  A MapR distribution of the Hadoop shell  A tool to submit jobs to the cluster from your workstation  Compatible with: – Windows – Mac – Linux  Permissions/Credentials the same as the cluster Work with the cluster from your laptop© 2012 MapR Technologies Accessing your Cluster 9
  • Exercise: The MapR Client  Install the MapR Client  Submit a MapReduce job to the cluster from your client© 2012 MapR Technologies Accessing your Cluster 10
  • Direct Access NFS© 2012 MapR Technologies Accessing your Cluster 11
  • Direct Access NFS  Drag and drop  Open files and apps  Watch live data come in  Fully read/write  Multiple concurrent reads/writes  Easy to get data in/out  Same namespace paths as Hadoop  Mount with -o tcp,ver=3,nolock Mount a cluster like a disk!© 2012 MapR Technologies Accessing your Cluster 12
  • Exercise: NFS  Install an NFS client  Mount the cluster via NFS  Copy a text file to the cluster filesystem© 2012 MapR Technologies Accessing your Cluster 13
