------------------------------------

cdmikechen opened a new pull request #3378:
URL: https://github.com/apache/hudi/pull/3378


   ## What is the purpose of the pull request
   
   This pull request let hive can read timestamp type column datas correctly.
   
   The problem was initially related to JIRA [HUDI-83](https://issues.apache.org/jira/browse/HUDI-83) and related issues on issue https://github.com/apache/hudi/issues/2544
   
   ## Brief change log
    
   -  Change `HoodieParquetInputFormat` to use a custom `ParquetInputFormat` named `HudiAvroParquetInputFormat`
   - In `HudiAvroParquetInputFormat` we use a custom `RecordReader` named `HudiAvroParquetReader`. In this class we use `AvroReadSupport` so that Hive can get parquet data with an avro GenericRecord.
   - Use `org.apache.hudi.hadoop.utils.HoodieRealtimeRecordReaderUtils.avroToArrayWritable` to transform GenericRecord to ArrayWriteable. At the same time, timestamp processing for different situations of hive2 and hive3 is added to this method.
   
   ## Verify this pull request
   
   This change added tests and can be verified as follows:
   `org.apache.hudi.hadoop.TestHoodieParquetInputFormat.testHoodieParquetInputFormatReadTimestamp`
