farmmamba resolved HDFS-17363.
------------------------------
Resolution: Not A Problem
> Avoid initializing unnecessary objects in method getBlockRecoveryCommand
> ------------------------------------------------------------------------
>
> Key: HDFS-17363
> URL: https://issues.apache.org/jira/browse/HDFS-17363
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Reporter: farmmamba
> Assignee: farmmamba
> Priority: Major
>
> In method getBlockRecoveryCommand, we have below codes:
> {code:java}
> else {
> rBlock = new RecoveringBlock(primaryBlock, recoveryInfos,
> uc.getBlockRecoveryId());
> if (b.isStriped()) {
> rBlock = new RecoveringStripedBlock(rBlock,
> uc.getBlockIndicesForSpecifiedStorages(storageIdx),
> ((BlockInfoStriped) b).getErasureCodingPolicy());
> } {code}
> It seems that we initialize RecoveringBlock object every time even though
> b.isStriped returns true.
> This is unnecessary.
