Arpit Agarwal commented on HDFS-4434:
-------------------------------------
Not an out of memory error. In
TestCheckpoint#testMultipleSecondaryNNsAgainstSameNN, these checks need to be
inside the try block.
{code}
// NN should have received new checkpoint
assertEquals(6, storage.getMostRecentCheckpointTxId());
// Validate invariant that files named the same are the same.
assertParallelFilesInvariant(cluster, ImmutableList.of(secondary1,
secondary2));
// NN should have removed the checkpoint at txid 2 at this point, but has
// one at txid 6
assertNNHasCheckpoints(cluster, ImmutableList.of(4,6));
{code}
Ditto for testMultipleSecondaryNNsAgainstSameNN2.
