Andrew Purtell commented on HBASE-6345:
---------------------------------------
I have a vague memory of hearing that HDFS was moving away from the FI stuff.
> Utilize fault injection in testing using AspectJ

> Key: HBASE-6345
> URL: https://issues.apache.org/jira/browse/HBASE-6345
> Project: HBase
> Issue Type: Bug
> Reporter: Zhihong Ted Yu
>
> HDFS uses fault injection to test pipeline failure in addition to mock, spy.
> HBase uses mock, spy. But there are cases where mock, spy aren't convenient.
> Some example from DFSClientAspects.aj :
> {code}
> pointcut pipelineInitNonAppend(DataStreamer datastreamer):
> callCreateBlockOutputStream(datastreamer)
> && cflow(execution(* nextBlockOutputStream(..)))
> && within(DataStreamer);
> after(DataStreamer datastreamer) returning :
> pipelineInitNonAppend(datastreamer) {
> LOG.info("FI: after pipelineInitNonAppend: hasError="
> + datastreamer.hasError + " errorIndex=" + datastreamer.errorIndex);
> if (datastreamer.hasError) {
> DataTransferTest dtTest = DataTransferTestUtil.getDataTransferTest();
> if (dtTest != null)
> dtTest.fiPipelineInitErrorNonAppend.run(datastreamer.errorIndex);
> }
> }
> {code}
