Jing Zhao commented on HDFS-9180:
---------------------------------
To help testing the patch, we can add the following test in
{{TestDFSStripedOutputStreamWithFailure}}:
{code}
@Test
public void testDataFailureWithAllLengths() throws Exception {
for (int length : LENGTHS) {
LOG.info("run test with length: " + length);
runTest(length);
}
}
{code}
The test may take a couple of hours.

> This is a TODO in HDFS-9040: based on the failures all the striped data

> DataNodes that should be excluded.

> provide more details in the comment.
