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` ## Committer checklist - [x] Has a corresponding JIRA in PR title & commit - [ ] Commit message is descriptive of the change - [ ] CI is green - [ ] Necessary doc changes done or have another open PR - [ ] For large changes, please consider breaking it into sub-tasks under an umbrella JIRA. -- This is an automated message from the Apache Git Service.
