execute hive query hangs

When use the pyhive to execute the SQL, the execution takes more than 25 minutes, causing a hang problem that prevents the program from proceeding to the next step, even though the hive job has been executed. I use dtruss to trace the python program about kernel calls，and found that the python side did not receive the socket-related packages.
-----------------------------------------------------
nomal kernel call:
SYSCALL(args) = return
recvfrom(0x5, 0x10274AC20, 0x6D) = 109 0
sendto(0x5, 0x102798518, 0x64) = 100 0
recvfrom(0x5, 0x102750C80, 0x4) = 4 0
recvfrom(0x5, 0x10278F5A0, 0x2A) = 42 0
sendto(0x5, 0x10272EA28, 0x57) = 87 0
recvfrom(0x5, 0x102750E38, 0x4) = 4 0
recvfrom(0x5, 0x10278F5F0, 0x28) = 40 0
close(0x5) = 0 0

abnormal kernel call：
SYSCALL(args) = return
^C

Env:
external programs use iptables to access Hive in private networks.
