      Description

      Currently we use TreeMap for corruptReplicasMap, actually the only need sorted place is getCorruptReplicaBlockIds which is used by test.
      So we can use HashMap.

      From memory and performance view, HashMap is better than TreeMap, a simliar optimization HDFS-7433. Of course we need to make few change to getCorruptReplicaBlockIds.

        TestCorruptReplicaInfo can be as the regression test.

        Hi Yi Liu, thanks for starting this effort.

        Of course we need to make few change to getCorruptReplicaBlockIds.

        Do you mean an additional fix to getCorruptReplicaBlockIds beyond your current patch is needed? It looks like getCorruptReplicaBlockIds won't work in general since it assumes the map is sorted. Can you add an @VisibleForTesting annotation and also rename the function to getCorruptReplicaBlockIdsForTesting so this function is not used inadvertently?

        +1 otherwise, pending Jenkins.

        Thanks Arpit Agarwal for review!

        Actually I have added @VisibleForTesting annotation for getCorruptReplicaBlockIds, I can certainly rename it as you suggestion in next patch.

        It looks like getCorruptReplicaBlockIds won't work in general since it assumes the map is sorted

        You are right, I have fixed this too in the current patch, so no need additional fix, look at following code, it uses a TreeMap wrapper in getCorruptReplicaBlockIds. The Jenkins result also shows the fix correct.

        +    Iterator<Block> blockIt = 
        +        new TreeMap<>(corruptReplicasMap).keySet().iterator();

        Sorry for missing that I should have looked more carefully. The test failures look unrelated.

        +1 from me. Feel free to commit after renaming the function!

        Arpit Agarwal, no problem, thanks a lot for the review! Update the patch to rename getCorruptReplicaBlockIds, it's a good idea then the function is not used inadvertently.
