custom authentication handler being run for /imagetransfer endpoint
Zbigniew Kostrzewa created HDFS-15860:
-----------------------------------------
Summary: Namenode bootstrap fails due to custom authentication handler being run for /imagetransfer endpoint
Key: HDFS-15860
URL: https://issues.apache.org/jira/browse/HDFS-15860
Project: Hadoop HDFS
Issue Type: Bug
Components: ha
Affects Versions: 3.3.0
Environment: CentOS Linux release 7.7.1908 (Core)
Reporter: Zbigniew Kostrzewa
I have extended Hadoop (YARN, HDFS, ...) web UIs with basic authentication by implementing a custom authentication handler class and configuring it via `hadoop.http.authentication.type` in core-site.xml.
Everything was working fine with Hadoop 2.x and 3.2.2. However, when I tried switching to 3.3.0 standby Namenode failed during bootstrap when trying to get fsimage:

It seems that in 3.3.0 my custom handler was being invoked for `/imagetransfer` endpoint, from active NN:

which was not the case for 3.2.2 and earlier.
