Description

While the graceful shutdown deadline can be configured when the SHUTDOWN() statement is executed, when the shutdown is initiated with SIGTERMIN signal it will use a default 1 year deadline. The related ImpalaShutdownSignalHandler can be found here.

...
const int ONE_YEAR_IN_SECONDS = 365 * 24 * 60 * 60;
Status status = impala_server->StartShutdown(ONE_YEAR_IN_SECONDS, &shutdown_status);
...

The --shutdown_deadline_s flag should be respected in this case as well.
