Anbang Hu commented on HDFS-13569:
----------------------------------
Thank [~giovanni.fumarola] and [~elgoiri] for your kind review. Since this test
class does not fail in daily Windows build. Let's keep it as it is. The reason
for local timeout is that DNS resolution for fully qualified domain name on
Windows takes a long time. The workaround is to add those IPs explicitly to
hosts file. For example, run the following in Powershell as Admin before
testing Hadoop will do the trick:
{code:java}
netsh interface ip show address | findstr "IP Address" | ForEach
{$_.Split(":")[-1] + " localhost"} > C:\Windows\System32\drivers\etc\hosts
{code}
> TestDataNodeMultipleRegistrations#testClusterIdMismatchAtStartupWithHA times
> out intermittently on Windows
