[GitHub] [hadoop] steveloughran commented on pull request #2206: HADOOP-17038 Support positional read in AbfsInputStream

   As discussed, I don't like this design.
   
   It's optimised purely for the current API uses which HBase makes, is brittle to any changes there and doesn't provide any way to explicitly tune things.
   
   Please add openFile to the ABFS Store and use that as a way to explicitly allow the caller to specify positioned read policy; HBase can then use the right option at the right point. We could backport that API to hadoop-3.2.x if that would aid there
