@tzulitai Thank you for your reply. For 2, I think a new issue may be
created later.
For 1, it is really a problem for which will block the running job. There
may be two ways:
1. Depend on the timeout mechanism of kafka. When fetching partition meta
from kafka, some timeout configurations should be setted.
2. Using Future to get the partiton meta of kafka, and user can set the
timeout with configuration.
For the 1th way, problem may still exist for network and other reasons, so
I'm apt to use the 2ed way.
