Shengkai Fang commented on FLINK-30978:
---------------------------------------
After discussing with colleagues, I find the problem is because the
`RestClient#sendRequest` and `CompletableFuture#get` are not atomic. The Client
may send the request and the Server returns the response immediately before
ExecutorImpl tries to invoke `CompletableFuture#get`. In this case, the
Executor will not check the interrupted flag on the thread and continue
execution here.
> ExecutorImplITCase.testInterruptExecution hangs waiting for SQL gateway
