Starting from EEP 8.1.0, EEP 7.1.2, and EEP 6.3.6, to remove the temporary Hive files created
during the Hive session, set the value of
hive.scratchdir.lock
property to
true
on hive-site.xml
file.<property>
<name>hive.scratchdir.lock</name>
<value>true</value>
</property>
For the previous EEP versions, manually remove the temporary Hive files that are not used by the active Hive sessions.

-
If you have configured the HiveServer2 in a node, set
hive.scratchdir.lock
property on thehive-site.xml
file to automatically remove the temporary Hive files. -
If you have not configured the HiveServer2 in a node, set the
hive.scratchdir.lock
property and run the following command to remove the temporary Hive files.hive --service cleardanglingscratchdir
