---------------------------------
Summary: Partitioned tables migrated to Iceberg aren't cached in
LLAP
Key: HIVE-25955
URL: https://issues.apache.org/jira/browse/HIVE-25955
Project: Hive
Issue Type: Bug
Reporter: Ádám Szita
Assignee: Ádám Szita
Files of migrated partitioned tables don't contain partition values, however
Iceberg's read schema has them. The difference between this read schema and
file schema is considered an unsupported schema evolution by LlapRecordReader
so it bails out before starting to read.
We should remove identity partition column names from the read the schema, if
we find that it's a not an Iceberg-written (so is migrated) file.
