Ethan Guo commented on HUDI-3050:
---------------------------------
[~kinger0610] On which Hudi version do you hit this? Looking at the code, the
exception is thrown when the write client is trying to start the timeline
service without the hostname so the dummy host is generated, which fails. In
this case, maybe "google.com" cannot be resolved so it failed. There is one
fix around that on master: [https://github.com/apache/hudi/pull/4355/files.]
Could you try it?
