Hi, @HyukjinKwon . This is a security feature and Apache ORC [CryptoUtils](https://github.com/apache/orc/blob/master/java/core/src/java/org/apache/orc/impl/CryptoUtils.java#L158) creates the key provider from its [Singleton Hadoop Shims Factory](https://github.com/apache/orc/blob/master/java/core/src/java/org/apache/orc/impl/HadoopShimsFactory.java#L50). If the other non-secured ORC code creates this without a proper configuration first, it will get [NullKeyProvider](https://github.com/apache/orc/blob/b05350a384dd92e2f8579f9997d1d9b36b7fcb68/java/shims/src/java/org/apache/orc/impl/HadoopShimsPre2_7.java#L225) and affects all the subsequent test cases. > Do we know the reason why it needs to run the test in a separate forked JVM to pass? Tag `DedicatedJVM` sounds better to me, too. I'll make a follow-up. > DedicatedJVM ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
