Why Does Metadata Still Exist When the HDFS Data Directory of the Hive Table Is Deleted by Mistake?

Question

The HDFS data directory of the Hive table is deleted by mistake, but the metadata still exists. As a result, an error is reported during task execution.

Answer

This is a exception caused by misoperation. You need to manually delete the metadata of the corresponding table and try again.

Example:

Run the following command to go to the console:

source ${BIGDATA_HOME}/FusionInsight_BASE_8.1.0.1/install/FusionInsight-dbservice-2.7.0/.dbservice_profile

gsql -p 20051 -U hive -d hivemeta -W HiveUser@

Run the delete from tbls where tbl_id='xxx'; command.
