See Jira item for users' guide. Editorial pass over all release notes prior to publication of 0.21. > Add orthogonal fault injection mechanism/framework > -------------------------------------------------- > > Key: HDFS-435 > URL: https://issues.apache.org/jira/browse/HDFS-435 > Project: Hadoop HDFS > Issue Type: Test > Components: test > Reporter: Konstantin Boudnik > Assignee: Konstantin Boudnik > Attachments: Fault injection development guide and Framework HowTo.pdf, Fault injection development guide and Framework HowTo.pdf > > > It'd be great to have a fault injection mechanism for Hadoop. > Having such solution in place will allow to increase test coverage of error handling and recovery mechanisms, reduce reproduction time and increase the reproduction rate of the problems. > Ideally, the system has to be orthogonal to the current code and test base. E.g. faults have to be injected at build time and would have to be configurable, e.g. all faults could be turned off, or only some of them would be allowed to happen. Also, fault injection has to be separated from production build. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
