Hello Lars Volker, Laszlo Gaal, Michael Brown, Zoltan Borok-Nagy, Philip Zeyliger, David Knupp, Attila Jeges, Tim Armstrong, Csaba Ringhofer,
I'd like you to reexamine a change. Please visit http://gerrit.cloudera.org:8080/8549 to look at the new patch set (#6). Change subject: IMPALA-1144: Fix exception when cancelling query in Impala-shell with CTRL-C ...................................................................... IMPALA-1144: Fix exception when cancelling query in Impala-shell with CTRL-C Issue1: When query is cancelled via CTRL-C while being executed in Impala-shell then an exception is thrown from Impala backend saying 'Invalid query handle'. This is because one ImpalaClient was making RPC's while another ImpalaClient cancelled the query on the backend. As a result RPC handlers in ImpalaServer try to access a ClientRequestState that had been cleared from the backend. The issue is confidently reproducable both in wait_to_finish and in fetch states of the query. As a solution the query cancellation is indicated to ImpalaClient via a bool flag. Once a cancellation originated exception reaches Impala shell this flag is checked to decide whether to suppress the error or not. Issue2: Every time a query was cancelled a 'use db' command was issued automatically. This happened to historical reasons but is not needed anymore (see Jira for more details).
