[jira] [Created] (HIVE-26612) Hive cannot read parquet files with int64 (TIMESTAMP_MILLIS)

Steve Carlin created HIVE-26612:
-----------------------------------

             Summary: Hive cannot read parquet files with int64 (TIMESTAMP_MILLIS)
                 Key: HIVE-26612
                 URL: https://issues.apache.org/jira/browse/HIVE-26612
             Project: Hive
          Issue Type: Bug
          Components: Database/Schema
            Reporter: Steve Carlin


If a parquet file has a Type of "int64 eventtime (TIMESTAMP(MILLIS,true))", the following error is produced:

exec.Task: Failed with exception java.io.IOException:org.apache.parquet.io.ParquetDecodingException: Can not read value at 1 in block 0 in file file:/home/steve/upstream/hive/itests/qtest/target/tmp/parquet_format_ts_as_bigint/part-00000/timestamp_as_bigint.parquet
java.io.IOException: org.apache.parquet.io.ParquetDecodingException: Can not read value at 1 in block 0 in file file:/home/steve/upstream/hive/itests/qtest/target/tmp/parquet_format_ts_as_bigint/part-00000/timestamp_as_bigint.parquet

        at org.apache.hadoop.hive.ql.exec.FetchTask.execute(FetchTask.java:98)

The parquet file can be created with the following steps (through spark):



spark.conf.set("spark.sql.parquet.outputTimestampType", "TIMESTAMP_MILLIS")
spark.conf.set("spark.sql.legacy.parquet.int96RebaseModeInWrite", "LEGACY")
spark.conf.set("spark.sql.legacy.parquet.datetimeRebaseModeInWrite", "LEGACY")
spark.conf.set("spark.sql.legacy.parquet.int96RebaseModeInRead", "LEGACY")
spark.conf.set("spark.sql.legacy.parquet.datetimeRebaseModeInRead", "LEGACY")
