Eli Collins commented on HDFS-2136: ----------------------------------- @Matt, #2 means the code contains hooks for generating a fault/behavior and the test code triggers the hooks. See the test he referenced for an example. @Cos, maybe you and Matt could sync up and you could write an AOP test for a case Matt is thinking of to compare against. > 1073: Fault injection for StorageDirectory failures during read/write of > FSImage/Edits files > -------------------------------------------------------------------------------------------- > > Key: HDFS-2136 > URL: https://issues.apache.org/jira/browse/HDFS-2136 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Matt Foley > > Both HDFS-1955 and HDFS-2135 have observed that it is difficult to unit test > such failures. As a result, regression of HDFS-1955 was only found by > careful manual review (thanks, atm!). Since 1073 is making broad changes to > the way these files are read and written, and appropriately putting effort > into correct error handling, I propose we make also make it possible to > auto-test that error handling. -- This message is automatically generated by JIRA.
