The test of test_query_cancellation_during_wait_to_finish failed in a recent build with the following error message.
The error message was produced at https://github.com/apache/impala/blame/master/tests/shell/test_shell_commandline.py#L418 in wait_for_query_state(), which is authored by Gabor Kaszab. Maybe you could offer some insight into it? Assign the JIRA to you for now but please feel free to assign it to other as you see appropriate. Tagged Tim Armstrong here since Tim also helped with reviewing the patch (https://gerrit.cloudera.org/c/8713/). Thanks!
