It isn't just custom authentication. Hadoop's [FileSystem](https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java) is an abstract class and users can extend the concrete implementations available or implement their own. One use case is to provide an implementation to a custom object store. Another use case is to extended an existing implementation to provide stricter access to individual files. Both Spark and Hadoop allow an end user to use such a custom implementation. To support this we will end up having to implement a JNI layer to access the entire FileSystem API. Neither this, nor custom auth is a hard requirement for OpenDAL to be supported by Comet. We can have both fs-hdfs and OpenDAL as options to access HDFS. OpenDAL provides us with the ability to access storage systems beyond HDFS while fs-hdfs provides us with more specialized Hadoop specific functionality. -- This is an automated message from the Apache Git Service.
