------------------------------------
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`
