Hello Tamas Mate, Csaba Ringhofer, Impala Public Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/18368 to look at the new patch set (#3). Change subject: IMPALA-11210: Impala can only handle lowercase schema elements of Iceberg table ...................................................................... IMPALA-11210: Impala can only handle lowercase schema elements of Iceberg table When Impala/Hive creates a table they lowercase the schema elements. When Spark creates an Iceberg table it doesn't lowercase the names of the columns in the Iceberg metadata. This triggers a precondition check in Impala which makes such Iceberg tables unloadable. This patch converts column names to lowercase when converting Iceberg schemas to Hive/Impala schemas.
