Impala external table partitions still show up in stats with row count 0 after deleting the data in HDFS and altering (like ALTER TABLE table RECOVER PARTITIONS) refreshing (REFRESH table) and invalidation of metadata.
Trying to drop partitions one by one works, but there are tens of partitions which should be removed and it would be quite tedious.
Dropping and recreating the table would also be an option but that way all the statistics would be dropped together with the table.
Is there any kind of other options in impala to get this done?
Is this only a workaround using Hive below?
