Csaba Ringhofer updated IMPALA-12987:
-------------------------------------
Description:
Inserting strings with "\0" values to partition columns leads errors both in
Iceberg and Hive tables.
The issue is more severe in Iceberg tables as from this point the table can't
be read in Impala or Hive:
{code}
create table iceberg_unicode (s string, p string) partitioned by spec
(identity(p)) stored as iceberg;
insert into iceberg_unicode select "a", "a\0a";
ERROR: IcebergTableLoadingException: Error loading metadata for Iceberg table
hdfs://localhost:20500/test-warehouse/iceberg_unicode
CAUSED BY: TableLoadingException: Refreshing file and block metadata for 1
paths for table default.iceberg_unicode: failed to load 1 paths. Check the
catalog server log for more details.
{code}
In partition Hive tables the insert also returns an error, but the new
partition is not created and the table remains usable. The error is similar to
IMPALA-11499's
