Table Data Is Empty on the TezUI HiveQueries Page
Question
A user logs in to Manager and switches to the Tez web UI page, but no data for the submitted task is displayed on the Hive Queries page.
Answer
To display Hive Queries task data on the Tez web UI, you need to set the following parameters:
On Manager, choose Cluster > Service > Hive > Configurations > All Configurations > Hive > Customization. Add the following configuration to yarn-site.xml:
| Attribute | Attribute Value |
|---|---|
| yarn.timeline-service.enabled | true |
| yarn.timeline-service.webapp.https.address | #{tl_hostname}:#{tl_https_port} |
| yarn.resourcemanager.system-metrics-publisher.enabled | true |
| yarn.timeline-service.generic-application-history.enabled | true |
On Manager, choose Cluster > Service > Hive > Configurations > All Configurations > HiveServer > Customization. Add the following configuration to hive-site.xml:
| Attribute | Attribute Value |
|---|---|
| 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 |
Data display on TezUI depends on the TimelineServer instance of Yarn. If the TimelineServer instance is faulty or not started, you need to set yarn.timeline-service.enabled to false in yarn-site.xml. Otherwise, the Hive task fails to be executed.
