Description

Before the DataNode(s) reporting bad block(s), when Client reads the EC file which has bad blocks, Client gets hung up. And there are no error messages.
(When Client reads the replicated file which has bad blocks, the bad blocks are reconstructed at the same time, and Client can reads it.)
