Description

The Pig tests seem to be running very slowly (several minutes), and CPU is idle.

A thread dump reveals a wait in java.net.Inet6AddressImpl#lookupAllHostAddr. If so, maybe we’re hitting a known problem when IPv6 is not available.

The fix would be to add -Djava.net.preferIPv4Stack=true.

maryannxue, Can you please see whether that fix helps in your environment?
