Kai Zheng commented on HDFS-8450: --------------------------------- Thanks Rakesh again for the update. More comments, would you help check one more time? Thanks! 1. {{ErasureCodingZoneManager}} mostly uses {{iip}} instead of {{src}} except {{createErasureCodingZone}}, so better to refactor it? Thus {{FSDirErasureCodingOp#createErasureCodingZone}} can also be simplified, using the utility {{getINodesInPath}}. 2. I don't quite like passing {{fsd}} and {{ecManager}}, instead just passing {{fsn}} is good enough. Please check other places. {code} + private static ErasureCodingZone getErasureCodingZone(final FSDirectory fsd, + final INodesInPath iip, final ErasureCodingZoneManager ecManager) + throws IOException { {code} 3. How about changing {{fsn.getECSchemaManager}} this time together?
