Hi Vinoth, I tried your second suggestion and it worked
>>> B) Try to shade/bundle more jars to try and make master work. Current bundles don't include parquet - either in utilities-bundle for hive syncing or mr-bundle for queries. This amounts to including jars https://github.com/apache/incubator-hudi/blob/master/packaging/hudi-hadoop-mr-bundle/pom.xml#L66 here. Just putting down points that I followed 1. Changed to Hive 1.1 and modified relevant classes, here's the diff [1] 2. But even after modifying the relevant classes and building, I was hitting into the same error, then I stumbled into this PR [2]. I followed the same and commented out the relocation patterns, and it worked. Just couldn't understand how shading could cause ClassCastExceptions.
