Review Comment:
@sodonnel Thank you for your reply.
In response to this question The data is EC in Ozone, but goes to a non EC
folder in HDFS - how will that work, and what will the replication factor be
set to in HDFS? The result of my test is 3.
At this jira https://issues.apache.org/jira/browse/HADOOP-14254 add a "-pe"
switch to ensure erasure coded files at source are copied as erasure coded
files at destination.
But when I distcp specify -p HDFS EC to Ozone Ratis Bucket, The number of
replicas in ozone is neither ec nor RATIS-THREE, but Ratis-ONE.
In this pr
https://github.com/apache/hadoop/commit/c757cb61ebc9e69d9f6f143da91189b9f0517ee9#diff-6207b5e70af95b856263703af631c577358dd06662d364f06347827d92f734f2.
His conditions are very harsh, `sourceStatus instanceof HdfsFileStatus &&
targetFS instanceof DistributedFileSystem`
Only then will the ecPolicy attribute be obtained, which causes distcp to
cannot obtain the ecPolicy in the ozone.
