@ferhui Thanks for reviewing.
This does not seem to cause any problems in production,
However in this case the debug log output execution information is a
problem.
```java
BlockManager#computeReconstructionWorkForBlocks
int computeReconstructionWorkForBlocks(
List<List<BlockInfo>> blocksToReconstruct) {
...
if (blockLog.isDebugEnabled()) {
// log which blocks have been scheduled for reconstruction
for (BlockReconstructionWork rw : reconWork) {
DatanodeStorageInfo[] targets = rw.getTargets();
if (targets != null && targets.length != 0) {
StringBuilder targetList = new StringBuilder("datanode(s)");
for (DatanodeStorageInfo target : targets) {
targetList.append(' ').append(target.getDatanodeDescriptor());
}
blockLog.debug("BLOCK* ask {} to replicate {} to {}",
rw.getSrcNodes(),
rw.getBlock(), targetList);
}
...
```
