Description
Improve Hadoop's resilience to bad network conditions/problems, including
- improving recognition of problem states
- improving diagnostics
- better handling of IPv6 addresses, even if the protocol is unsupported.
- better behaviour client-side when there are connectivity problems. (i.e while some errors you can spin on, DNS failures are not on the list)
