Does REFRESH table command refresh the metadata in Impala when a partition location is changed in Hive?
I am changing the Hive table partition location using
ALTER TABLE db.table partition(key=value1, key2=value2) set location='path'
After that, I am running REFRESH db.table in Impala which is not updating metadata. If I run INVALIDATE METADATA it is working.
There is Impala JIRA-4364 open for that. However its been in product backlog since 2017, so currently INVALIDATE METADATA is the only workaround.
UPDATE: This has been fixed in Impala 4.0 (see same JIRA link above).
