Writing a Directory into Hive with the Old Data Removed to the Recycle Bin

Scenario

This function applies to Hive.

After this function is enabled, run the following command to write a directory into Hive: insert overwrite directory "/path1" .... After the operation is successfully performed, the old data is removed to the recycle bin, and the directory cannot be an existing database path in the Hive metastore.

  1. The Hive service configuration page is displayed.

    • For versions earlier than MRS 1.9.2, log in to MRS Manager, choose Services > Hive > Service Configuration, and select All from the Basic drop-down list.
    • For MRS 1.9.2 or later, click the cluster name on the MRS console, choose Components > Hive > Service Configuration, and select All from the Basic drop-down list.

      If the Components tab is unavailable, complete IAM user synchronization first. (On the Dashboard page, click Synchronize on the right side of IAM User Sync to synchronize IAM users.)

    • For MRS 3.x or later, log in to FusionInsight Manager. For details, see Accessing FusionInsight Manager (MRS 3.x or Later). And choose Cluster > Name of the desired cluster > Services > Hive > Configurations > All Configurations.

  2. Choose HiveServer(Role) > Customization, add a customized parameter to the hive-site.xml parameter file, set Name to hive.overwrite.directory.move.trash, and set Value to true. Restart all Hive instances after the modification.
