             Summary: StreamBlockInputStream can NPE on premature stream completion and masked failure in onNext error handling
                 Key: HDDS-15794
                 URL: https://issues.apache.org/jira/browse/HDDS-15794
             Project: Apache Ozone
          Issue Type: Bug
          Components: Ozone Client
            Reporter: Siyao Meng
            Assignee: Siyao Meng


I was looking into other things but this pops out. Figure I should raise a quick patch for this.

 

Same family as HDDS-15521:

(1) when the datanode ends the gRPC stream while the client awaits requested data, {{poll()}} returns null and {{readFromQueue()}} throws NPE, which also bypasses {{handleExceptions()}} retry/failover since it isn't an IOException

(2) the {{onNext}} error path throws {{IndexOutOfBoundsException}} building a 10-byte hex preview of payloads under 10 bytes before {{setFailed()}} records the real failure, and dereferences a possibly-null {{{}getResponse(){}}}.
