Eric Yang updated YARN-7605: ---------------------------- Attachment: YARN-7605.010.patch [~jianhe] Thank you for the review. Patch 10 fixed unused parameter clazz, the automatic unboxing of result variable, and improved handling of exception types. NullPointerException was supposed to guard against bad user input parameters. I have refactored the code to handle the possible null pointer exception at earlier stage. In ServiceClient, several methods shouldn't throw InterruptedException because AppAdminClient definition doesn't throw InterruptedException. This is the reason that InterruptedException were converted to YarnException. Formatting for createAMProxy, actionSave were to remove some check style issues that exist in ServiceClient. > Implement doAs for Api Service REST API > --------------------------------------- > > Key: YARN-7605 > URL: https://issues.apache.org/jira/browse/YARN-7605 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Eric Yang > Assignee: Eric Yang > Fix For: yarn-native-services > > Attachments: YARN-7605.001.patch, YARN-7605.004.patch, > YARN-7605.005.patch, YARN-7605.006.patch, YARN-7605.007.patch, > YARN-7605.008.patch, YARN-7605.009.patch, YARN-7605.010.patch > > > In YARN-7540, all client entry points for API service is centralized to use > REST API instead of having direct file system and resource manager rpc calls. > This change helped to centralize yarn metadata to be owned by yarn user > instead of crawling through every user's home directory to find metadata. > The next step is to make sure "doAs" calls work properly for API Service. > The metadata is stored by YARN user, but the actual workload still need to be > performed as end users, hence API service must authenticate end user kerberos > credential, and perform doAs call when requesting containers via > ServiceClient. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
