Lev Katzav created HIVE-23576:
---------------------------------
Summary: Getting partition of type int from metastore sometimes
fail on cast error
Key: HIVE-23576
URL: https://issues.apache.org/jira/browse/HIVE-23576
Project: Hive
Issue Type: Bug
Components: Hive, Standalone Metastore
Affects Versions: 3.1.2
Environment: metastore db - postgres (tried on 9.3 and 11.5)
Reporter: Lev Katzav
+pgiven the following situation:+
there are 2 tables (in db "intpartitionbugtest"), each with a few rows:
# *test_table_int_1* partitioned by *y* of type *int*
# *test_table_string_1* partitioned by *x* of type *string*
here is the output of the following query on the metastore db:
{code:sql}
select
"PARTITIONS"."PART_ID",
"TBLS"."TBL_NAME",
"FILTER0"."PART_KEY_VAL",
"PART_NAME"
from
"PARTITIONS"
inner join "TBLS" on
"PARTITIONS"."TBL_ID" = "TBLS"."TBL_ID"
inner join "DBS" on
"TBLS"."DB_ID" = "DBS"."DB_ID"
inner join "PARTITION_KEY_VALS" "FILTER0" on
"FILTER0"."PART_ID" = "PARTITIONS"."PART_ID"
{code}
!image-2020-05-29-14-15-44-756.png!
+the problem+
when running a hive query on the table *test_table_int_1* that filters on *y=1*
sometimes the following exception will happen on the metastore
{code:java}
javax.jdo.JDODataStoreException: Error executing SQL query "select
"PARTITIONS"."PART_ID" from "PARTITIONS" inner join "TBLS" on
"PARTITIONS"."TBL_ID" = "TBLS"."TBL_ID" and "TBLS"."TBL_NAME" = ? inner
join "DBS" on "TBLS"."DB_ID" = "DBS"."DB_ID" and "DBS"."NAME" = ? inner
join "PARTITION_KEY_VALS" "FILTER0" on "FILTER0"."PART_ID" =
"PARTITIONS"."PART_ID" and "FILTER0"."INTEGER_IDX" = 0 where "DBS"."CTLG_NAME"
= ? and (((case when "FILTER0"."PART_KEY_VAL" <> ? then
cast("FILTER0"."PART_KEY_VAL" as decimal(21,0)) else null end) = ?))".

{code}
the query that is failing is generated by:
org.apache.hadoop.hive.metastore.MetaStoreDirectSql.getPartitionsViaSqlFilterInternal
here is the query with the parameters added:
{code:sql}
select
"PARTITIONS"."PART_ID"
from
"PARTITIONS"
inner join "TBLS" on
"PARTITIONS"."TBL_ID" = "TBLS"."TBL_ID"
and "TBLS"."TBL_NAME" = 'test_table_int_1'
inner join "DBS" on
"TBLS"."DB_ID" = "DBS"."DB_ID"
and "DBS"."NAME" = 'intpartitionbugtest'
inner join "PARTITION_KEY_VALS" "FILTER0" on
"FILTER0"."PART_ID" = "PARTITIONS"."PART_ID"
and "FILTER0"."INTEGER_IDX" = 0
where
"DBS"."CTLG_NAME" = 'hive'
and
((
(
case
when "FILTER0"."PART_KEY_VAL" <> '__HIVE_DEFAULT_PARTITION__'
then cast("FILTER0"."PART_KEY_VAL" as decimal(21, 0))
else null end) = 1))
{code}
the query is failing on the casting to decimal of the string partition values
(a,b,c)
