#39 0x000000000041bb31 in _start (){code}The impala-shell processes have the 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.
