[jira] [Updated] (HIVE-6785) query fails when partitioned table's table level serde is ParquetHiveSerDe and partition level serde is of different SerDe
[ https://issues.apache.org/jira/browse/HIVE-6785?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Brock Noland updated HIVE-6785: --- Resolution: Fixed Status: Resolved (was: Patch Available) Committed to trunk! Thank you for the contribution! Thank you Szehon for the review! query fails when partitioned table's table level serde is ParquetHiveSerDe and partition level serde is of different SerDe -- Key: HIVE-6785 URL: https://issues.apache.org/jira/browse/HIVE-6785 Project: Hive Issue Type: Bug Components: File Formats, Serializers/Deserializers Affects Versions: 0.13.0 Reporter: Tongjie Chen Assignee: Tongjie Chen Fix For: 0.14.0 Attachments: HIVE-6785.1.patch.txt, HIVE-6785.2.patch.txt, HIVE-6785.3.patch When a hive table's SerDe is ParquetHiveSerDe, while some partitions are of other SerDe, AND if this table has string column[s], hive generates confusing error message: Failed with exception java.io.IOException:java.lang.ClassCastException: parquet.hive.serde.primitive.ParquetStringInspector cannot be cast to org.apache.hadoop.hive.serde2.objectinspector.primitive.SettableTimestampObjectInspector This is confusing because timestamp is mentioned even if it is not been used by the table. The reason is when there is SerDe difference between table and partition, hive tries to convert objectinspector of two SerDes. ParquetHiveSerDe's object inspector for string type is ParquetStringInspector (newly introduced), neither a subclass of WritableStringObjectInspector nor JavaStringObjectInspector, which ObjectInspectorConverters expect for string category objector inspector. There is no break statement in STRING case statement, hence the following TIMESTAMP case statement is executed, generating confusing error message. see also in the following parquet issue: https://github.com/Parquet/parquet-mr/issues/324 To fix that it is relatively easy, just make ParquetStringInspector subclass of JavaStringObjectInspector instead of AbstractPrimitiveJavaObjectInspector. But because constructor of class JavaStringObjectInspector is package scope instead of public or protected, we would need to move ParquetStringInspector to the same package with JavaStringObjectInspector. Also ArrayWritableObjectInspector's setStructFieldData needs to also accept List data, since the corresponding setStructFieldData and create methods return a list. This is also needed when table SerDe is ParquetHiveSerDe, and partition SerDe is something else. -- This message was sent by Atlassian JIRA (v6.2#6252)
