Either they are configured or hardcoded, IMHO, we should expose the information to users. For example, if the user input a tag which is too long to be accepted, RM should return with a suitable exception. In addition, I think It's also good to regulate the charset that the tag can use, avoid users to input some strange characters. Moreover, in general, IMHO, user name, queue name, application name and application type should be regulated as well. Thoughts. > Allow users to annotate an application with multiple tags > --------------------------------------------------------- > > Key: YARN-1399 > URL: https://issues.apache.org/jira/browse/YARN-1399 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Zhijie Shen > Assignee: Zhijie Shen > > Nowadays, when submitting an application, users can fill the applicationType field to facilitate searching it later. IMHO, it's good to accept multiple tags to allow users to describe their applications in multiple aspects, including the application type. Then, searching by tags may be more efficient for users to reach their desired application collection. It's pretty much like the tag system of online photo/video/music and etc. -- This message was sent by Atlassian JIRA (v6.1#6144)
