Ádám Szita updated HIVE-26189:
------------------------------
Description:
The following test case surfaced two issues with metadata table queries:
{code:java}
CREATE EXTERNAL TABLE `partevv`( `id` int, `ts` timestamp, `ts2` timestamp)
STORED BY ICEBERG STORED AS ORC TBLPROPERTIES ('format-version'='1');
ALTER TABLE partevv SET PARTITION SPEC (id);
INSERT INTO partevv VALUES (1, current_timestamp(), current_timestamp());
INSERT INTO partevv VALUES (2, current_timestamp(), current_timestamp());
ALTER TABLE partevv SET PARTITION SPEC (day(ts));
INSERT INTO partevv VALUES (100, current_timestamp(), current_timestamp());
select * from default.partevv.partitions; {code}
* NPE for removed partition columns from new specs
{code:java}
Caused by: java.lang.NullPointerException
at
org.apache.iceberg.mr.mapreduce.IcebergInternalRecordWrapper.lambda$converter$5(IcebergInternalRecordWrapper.java:147)
{code}
* for day partition transforms: java.lang.ClassCastException:
java.lang.Integer cannot be cast to java.time.LocalDate
