satishkotha opened a new pull request #1809: URL: https://github.com/apache/hudi/pull/1809
## What is the purpose of the pull request 1) InputFormat backward compatibility is broken in several places because equality check is done including package name in multiple places https://github.com/apache/hudi/blob/master/hudi-hadoop-mr/src/main/java/org/apache/hudi/hadoop/hive/HoodieCombineHiveInputFormat.java#L154. Fix this by using inheritance and using appropriate package name. 2) For 0.4.x versions, reading worked with ORCInputFormat as well. For 0.4.x, we used shim to read as opposed to throwing error for non-hoodie formats. Bring back same functionality to master. ## Brief change log - Fix InputFormat class lookup based on package name of source inputformat. - Do not throw error for non-hoodie input format and delegate reading to shim loader ## Verify this pull request Verified end-to-end in uber internal hive service deployment. ## 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.
