-------------------------------------
Summary: TTransportException can be thrown for RPC connection that
is open for long time
Key: IMPALA-11548
URL: https://issues.apache.org/jira/browse/IMPALA-11548
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 4.2.0
Reporter: Riza Suminto
Assignee: Riza Suminto
After Impala upgrade CPP thrift version to 0.16.0, we are seeing
TTransportException thrown for RPC connection that is open for long time.
thrift-0.16.0 add counter to limit message size at
[https://github.com/apache/thrift/commit/63213c1].
The TTransportException is thrown when remainingMessageSize < numBytes,
indicating that TTransport was not flushed properly.
This is presumably due to the fact that both input_ and output_ TProtocol
within TAcceptQueueServer::Task has different TTransport object within them.
Letting both input_ and output_to share the same TTransport object might fix
the flushing mechanism and properly reset the limit counter of the shared
TTransport.
