> following network connections:{code}TCP
> ec2-systest-slave-142f.test:48498->10.17.234.12:21000 (CLOSE_WAIT)
> UDP ec2-systest-slave-142f.test:51510->10.17.234.11:kerberos
> TCP ec2-systest-slave-142f.test:40665->10.17.234.11:kerberos
> (CLOSE_WAIT){code}However neither the KDC nor impalad show these connections.
> The impala-shell processes are using 100% CPU. These three system calls are
> being made in a tight loop:{code}poll([{fd=4, events=POLLIN}, {fd=5,
> events=POLLIN}], 2, -106519201) = 1 ([{fd=5, revents=POLLIN}])
> read(5, "", 4) = 0
> gettimeofday({1508277815, 791798}, NULL) = 0{code}It looks like this is a
> version 2.9.0 impala-shell running against a version 2.11.0 (pre-release)
> server.
