Alexander Behm created IMPALA-6627: -------------------------------------- Summary: Document Hive-incompatible behavior with the serialization.null.format table property Key: IMPALA-6627 URL: https://issues.apache.org/jira/browse/IMPALA-6627 Project: IMPALA Issue Type: Improvement Components: Docs Reporter: Alexander Behm Assignee: Alex Rodoni
Impala only respects the "serialization.null.format" table property for TEXT tables and ignores it for Parquet and other formats. Hive respects the "serialization.null.format" property even for other formats, converting matching values to NULL during the scan. There's is a separate discussion to be had about which behavior makes more sense, but let's document this as an incompatibility for now since it has come up several times already. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
