Larry McCay commented on HADOOP-15808: -------------------------------------- [~ste...@apache.org] - what is the difference between no class found and not being able to be instantiated - they are separate exceptions but wondering whether the javadoc is correct in... + * @return the token identifier, or null if there was no class found for it + * @throws IOException failure to unmarshall the data + * @throws RuntimeException if the token class could not be instantiated. is it literally distinguishing between the two - so that a class that is found but cannot be loaded gets a runtime exception and a class not found gets a null returned? I assume once this gets in a patch for all of the consumers that will need to accommodate null will created? > Harden Token service loader use > ------------------------------- > > Key: HADOOP-15808 > URL: https://issues.apache.org/jira/browse/HADOOP-15808 > Project: Hadoop Common > Issue Type: Improvement > Components: security > Affects Versions: 2.9.1, 3.1.2 > Reporter: Steve Loughran > Assignee: Steve Loughran > Priority: Major > Attachments: HADOOP-15808-001.patch, HADOOP-15808-002.patch, > HADOOP-15808-003.patch > > > The Hadoop token service loading (identifiers, renewers...) works provided > there's no problems loading any registered implementation. If there's a > classloading or classcasting problem, the exception raised will stop all > token support working; possibly the application not starting. > This matters for S3A/HADOOP-14556 as things may not load if aws-sdk isn't on > the classpath. It probably lurks in the wasb/abfs support too, but things > have worked there because the installations with DT support there have always > had correctly set up classpaths. > Fix: do what we did for the FS service loader. Catch failures to instantiate > a service provider impl and skip it -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
