In impala4.0, if the query execution takes too long and exceeds the FETCH_ROWS_TIMEOUT_MS time, the FetchResults rpc will return the STILL_EXECUTING status. However, since no error is thrown and no retry is performed at this time, a null pointer may appear when using the results externally. This modification retried the FetchResults rpc when the STILL_EXECUTING state occurred.
