Have clarified the behavior in the docs. A value of 0 should cause the fetch request to wait indefinitely.

Yes, FetchInternal always sets the statusCode, unless it returns an error impala::Status, in which case the if loop above is triggered. If it reaches the end of the if without returning, than the statusCode is set to SUCCESS_STATUS. The change is necessary otherwise SUCCESS_STATUS is always returned, even if the statusCode was already set to STILL_EXECUTING_STATUS -- To view, visit http://gerrit.cloudera.org:8080/14332 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I2cba6bf062dcc1af19471d21857caa797c1ea4a4 Gerrit-Change-Number: 14332 Gerrit-PatchSet: 1 Gerrit-Owner: Sahil Takiar <[email protected]> Gerrit-Reviewer: Impala Public Jenkins <[email protected]> Gerrit-Reviewer: Sahil Takiar <[email protected]> Gerrit-Reviewer: Thomas Tauber-Marshall <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Comment-Date: Tue, 01 Oct 2019 21:36:29 +0000 Gerrit-HasComments: Yes
