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 task data on the Hive Queries page on the Tez web UI, you need to set the following parameters:
On FusionInsight Manager, choose Cluster > Service > Hive and click the Configurations tab and then All Configurations. In the navigation pane on the left, choose 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 |
Note
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.
After you configure the parameters and re-execute the Hive task, data can be displayed on the Hive Queries page. However, data of previous tasks cannot be displayed.
