Tez web UI

Tez has its own web user interface. To view the web UI, see the following URL.

http://masterDNS:8080/tez-ui

To enable the Hive Queries tab on the Tez web UI, set the following configuration.

[
  {
    "Classification": "hive-site",
    "Properties": {
      "hive.exec.pre.hooks": "org.apache.hadoop.hive.ql.hooks.ATSHook",
      "hive.exec.post.hooks": "org.apache.hadoop.hive.ql.hooks.ATSHook",
      "hive.exec.failure.hooks": "org.apache.hadoop.hive.ql.hooks.ATSHook"
    }
  }
]

You can also view Tez, Spark, and YARN application UI details using links on the Application user interfaces tab of a cluster's detail page in the console. Amazon EMR application user interfaces (UI) are hosted off-cluster and are available after the cluster has terminated. They don't require you to set up a SSH connection or web proxy, making it easier for you to troubleshoot and analyze active jobs and job history.

For more information, see View application history in the Amazon EMR Management Guide.
