Resolution: Duplicate
> Alter table recover partitions fails to detect changes in parent path
> ---------------------------------------------------------------------
>
> Key: IMPALA-3796
> URL: https://issues.apache.org/jira/browse/IMPALA-3796
> Project: IMPALA
> Issue Type: Bug
> Components: Catalog
> Affects Versions: Impala 2.3.0
> Reporter: Peter Ebert
> Priority: Minor
> Labels: ramp-up, usability
>
> If you have a table located at /db/table
> with partitions /db/table/partition=1
> and then move the table location to /db2/table/ along with the partitions and
> their data
> the location of the partitions will be incorrect when you list them, still
> pointing to /db/table/partition=1
> running a "Alter table recover partitions" seems to check only for the
> existence of partition=1 in the +current+ table location, and ignores that
> the prior path has changed. So when you run a query it will not find those
> partitions and report 0 rows.
> it should be noted that hive has the same behavior.
