### Description of PR
https://issues.apache.org/jira/browse/HDFS-17081
Append ec file check if a block is replicated to at least the minimum
replication need consider ec block.
currently only the minimum replication of the replica is considered, the
code is as follows:
/**
```
* Check if a block is replicated to at least the minimum replication.
*/
public boolean isSufficientlyReplicated(BlockInfo b) {
// Compare against the lesser of the minReplication and number of live
DNs.
final int liveReplicas = countNodes(b).liveReplicas();
if (liveReplicas >= minReplication) {
return true;
}
// getNumLiveDataNodes() is very expensive and we minimize its use by
// comparing with minReplication first.
return liveReplicas >= getDatanodeManager().getNumLiveDataNodes();
}
```
