Monitoring Hadoop Clusters

You can access reports that you use to monitor Hadoop clusters by clicking Hadoop Monitoring in the Tools menu.
After you select a server in the submenu, you can click one of the following reports to select it:
  • Job Tracker
  • Distributed file system viewer
  • Secondary distributed file system viewer
The Job Tracker report provides information about running and completing jobs. The two distributed file system viewer reports provide information about the nodes included in the Hadoop cluster. You can click the links provided in these reports to drill down for more details.
You can also right-click in a completed Pig or Map Reduce job and click Hadoop Job Statistics in the pop-up menu to access detailed statistics about the selected job.
