Andrew Wang commented on HADOOP-14726:
--------------------------------------
I did a grep and there's a lot of hits for "isDir(" in downstream projects:
Avro, Crunch, HBase, Hive, Hue, Kite, Oozie, Parquet, Pig, Sqoop, Zookeeper. I
think it's too late to remove at this point in the release cycle; if we're
serious about doing this for Hadoop 4, then let's file JIRAs for these
downstreams to switch over.
The idea of v000 seems okay to me too. It is still incompatible though, since
marking isDir {{final}} breaks out-of-tree FileSystems that override it. Is
this necessary?
