--------------------------------------
HI [~vinayrpet],
The test needs the following code to throw exception, but it's not guaranteed,
{code}
int count = 0;
while (count < 5) {
if (replicaInfo.getBytesAcked() < replicaInfo.getBytesOnDisk()) {
failed.set(true);
throw new IOException("Failing Pipeline " + replicaInfo
.getBytesAcked() + " : " + replicaInfo.getBytesOnDisk());
}
try {
Thread.sleep(200);
} catch (InterruptedException e) {
}
count++;
}
{code}
Maybe we can make {{count}} a little larger, and fail the test if the exception
is not generated after trying {{count}} times.
Thanks.
