## *Tips* - *Thank you very much for contributing to Apache Hudi.* - *Please review https://hudi.apache.org/contributing.html before opening a pull request.* ## What is the purpose of the pull request fix the bug that, HoodieCombineHiveInputFormat cannot build correct partition field. now hudi use HoodieCombineHiveInputFormat to achieve Incremental query of the mor table. when we have some small files in different partitions(file1 from partition p=6 , file2 from partition p=7), HoodieCombineHiveInputFormat will combine those small file readers. HoodieCombineHiveInputFormat build partition field base on the first file reader(assume file1 reader which from parition p=6) , however now HoodieCombineHiveInputFormat holds other file readers(file2 reader which from paritition p=7) which come from different partitions. When switching readers, we should update ioctx https://github.com/apache/hudi/blob/6e803e08b1328b32a5c3a6acd8168fdabc8a1e50/hudi-hadoop-mr/src/main/java/org/apache/hudi/hadoop/realtime/HoodieCombineRealtimeRecordReader.java#L73 ## Brief change log *(for example:)* - *Modify AnnotationLocation checkstyle rule in checkstyle.xml* ## Verify this pull request This pull request is already covered by existing tests, such as *(please describe tests)*. ## Committer checklist - [ ] 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.
