---------------------------------
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(){}}}.
