> HDFS-7369 adds the functionality to distribute recovery work of striped
> blocks to datanodes. There are still some pending issues:
> # In {{BlockManager#chooseSourceNode}}, a node is added into
> {{healthyIndices}} without checking if its block is live and healthy
> # The test {{TestRecoverStripedBlcoks#testMissingStripedBlock}} has not
> tested striped blocks because the file is created before setting the storage
> policy
> # In {{computeRecoveryWorkForBlocks}}, instead of using
> {{BlockCollection#isStriped}}, we'd better use {{BlockInfo#isStriped}}
