Oleksandr Shevchenko reassigned YARN-9000: ------------------------------------------ Assignee: Oleksandr Shevchenko > Add missing data access methods to webapp entities classes > ---------------------------------------------------------- > > Key: YARN-9000 > URL: https://issues.apache.org/jira/browse/YARN-9000 > Project: Hadoop YARN > Issue Type: Improvement > Reporter: Oleksandr Shevchenko > Assignee: Oleksandr Shevchenko > Priority: Minor > > From Hadoop side, we have entity classes which represent the data which can > be accessed via REST. All these classes are placed in .../webapp/dao packages > (for example > org.apache.hadoop.yarn.server.resourcemanager.webapp.dao.NodeInfo). > Typically these classes are created via constructors (some classes have > setters) in controllers and then is marshaled to XML/JSON format for data > transfer. Therefore, these classes are used more like as DTO. > We want to write some UI tests to verify the both YARN Web UIs (current ui > and ui2). We need to get some information from REST and compare with > information which displayed on UI. > The problem is we can't use for it the same entities from Hadoop. Because we > can't create these entities and set needed data from UI since many getters > and setters are missed. So, we will forced to write some layer which > represents the same data and exactly copies webapp/dao classes but includes > needed getters and setters. > Access methods are not unified. Some classes have only getters, some have > several setters, some have all the necessary getters and setters. In all > classes, we have a different set of methods, this is not controlled, new > methods are added as necessary. We open a lot of tickets for adding a > particular method to a particular class, this lead to some overhead. > In this ticket, I propose to unify access to the data and add all getters and > setters for all YARN webapp/dao classes (I will create a separated ticket for > MapReduce project if the idea will be approved and I will start working on > this issue). > Thanks a lot for any comments and attention to this problem! -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
