Description

Inserting into an existing partition, after changing a table's location to point to a different HDFS filesystem:

   query += "CREATE TABLE test_managed_tbl (id int, name string, dept string) PARTITIONED BY (year int);\n"
    query += "INSERT INTO test_managed_tbl PARTITION (year=2016) VALUES (8,'Henry','CSE');\n"
    query += "ALTER TABLE test_managed_tbl ADD PARTITION (year=2017);\n"
    query += "ALTER TABLE test_managed_tbl SET LOCATION 
                                  'hdfs://ns2/warehouse/tablespace/managed/hive/test_managed_tbl'"
    query += "INSERT INTO test_managed_tbl PARTITION (year=2017) VALUES (9,'Harris','CSE');\n"

Results in the following error:

java.lang.IllegalArgumentException: Wrong FS: hdfs://ns1/warehouse/tablespace/managed/hive/test_managed_tbl/year=2017, expected: hdfs://ns2
