> @satishkotha I have COW tables with data written by hoodie 0.4.6, I've now followed https://cwiki.apache.org/confluence/display/HUDI/Migration+Guide+From+com.uber.hoodie+to+org.apache.hudi steps and have done successful writes/reads with hudi 0.5.3 Without your PR where would I face issue? Hi, have you been using HoodieCombineHiveInputFormat for your use cases? As you can see in the diff, the fixes are specific to combine input format. When we ran queries after upgrading to new version(0.5.1), we got below errors 1) `Caused by: org.apache.hudi.exception.HoodieException: Unexpected input format : com.uber.hoodie.hadoop.HoodieInputFormat at org.apache.hudi.hadoop.hive.HoodieCombineHiveInputFormat.getRecordReader(HoodieCombineHiveInputFormat.java:522)` 2) `org.apache.hudi.exception.HoodieException: Unexpected input format : org.apache.hadoop.hive.ql.io.orc.OrcInputFormat at org.apache.hudi.hadoop.hive.HoodieCombineHiveInputFormat.getRecordReader(HoodieCombineHiveInputFormat.java:533)` With 0.4.x version same queries ran fine. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
