Work Description: vivekratnavel commented on issue #1201: HDDS-1788. Add
kerberos support to Ozone Recon
URL: https://github.com/apache/hadoop/pull/1201#issuecomment-517455963
Hi @bharatviswa504,
OzoneConfigurationProvider is changed to ConfigurationProvider in this patch
to have the correct `Configuration` object passed to the constructor of
`BaseHttpServer` here -
https://github.com/apache/hadoop/blob/trunk/hadoop-ozone/ozone-recon/src/main/java/org/apache/hadoop/ozone/recon/ReconHttpServer.java#L35
I understand that its not very clear because this class is not part of this
PR. The issue was that injection was not working in ReconHttpServer -
https://github.com/apache/hadoop/blob/trunk/hadoop-ozone/ozone-recon/src/main/java/org/apache/hadoop/ozone/recon/ReconHttpServer.java#L34
because of the use of Configuration object. Now, with refactoring
`OzoneConfigurationProvider` to `ConfigurationProvider` and changing this line
for bind -
https://github.com/apache/hadoop/pull/1201/files#diff-4a219a4368f56aa118b6ba4afb981244R57
fixes the injection in `ReconHttpServer` and thus Recon web server is able to
get access to the correct principal name and authenticate with kerberos ticket.
Please let me know if you have any more questions.
