Re: Block invalid IOException causes the DFSClient domain socket being disabled

Hi Xie Gang, Thanks for reporting the issue. How was the block invalidated on DN? I recently created a unit test that might trigger a somewhat similar symptom: 1. Read a 4000-byte file in MiniDFS. It should go thru domain socket. 2. Call input stream unbuffer. It will close the block
