Yushi Hayasaka commented on HDFS-15650:
---------------------------------------
Oh, I noticed we needed to change here too:
[https://github.com/apache/hadoop/blob/a55d6bba71c81c1c4e9d8cd11f55c78f10a548b0/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/FileChecksumHelper.java#L626].
However there is no way to get the configuration of timeout value in DN from
client (I think) now... Maybe that's why it is hard-coded?
