Walter Su commented on HDFS-9716:
---------------------------------
You can easily reproduce the failure by delay line 345 with a breakpoint or a
sleep, so NN has time to invalidate the replica.
{code}
339 // Check the replica on the new target node.
340 for (int i = 0; i < toRecoverBlockNum; i++) {
341 File replicaAfterRecovery = cluster.getBlockFile(targetDNs[i],
blocks[i]);
342 LOG.info("replica after recovery " + replicaAfterRecovery);
343 File metadataAfterRecovery =
344 cluster.getBlockMetadataFile(targetDNs[i], blocks[i]);
345 assertEquals(replicaAfterRecovery.length(), replicas[i].length());
346 LOG.info("replica before " + replicas[i]);
347 assertTrue(metadataAfterRecovery.getName().
348 endsWith(blocks[i].getGenerationStamp() + ".meta"));
349 byte[] replicaContentAfterRecovery =
350 DFSTestUtil.readFileAsBytes(replicaAfterRecovery);
351
352 Assert.assertArrayEquals(replicaContents[i],
replicaContentAfterRecovery);
353 }
354 }
