tasanuma commented on issue #1945: HDFS-15269. NameNode should check the authorization API version only … URL: https://github.com/apache/hadoop/pull/1945#issuecomment-611421431 Thanks for this PR, @jojochuang. I ran Dynamometer using the real workload of our largest cluster. After HDFS-14743, READ/WRITE performance degraded by 13~14%. Then, with this PR, the performance came back as before HDFS-14743. Thanks for working on this.
