Sergey Edunov created GIRAPH-1099:
-------------------------------------
Summary: Bypass all DNC calls in Giraph
Key: GIRAPH-1099
URL: https://issues.apache.org/jira/browse/GIRAPH-1099
Project: Giraph
Issue Type: Bug
Reporter: Sergey Edunov
Assignee: Sergey Edunov
After GIRAPH-1034 we have reduced the number of DNS lookups and reverse DNS
lookups dramatically. However, we still see failures occasionally and it would
be great to completely bypass DNS if PREFER_IP_ADDRESSES is set.
Currently I'm aware of two places that make DNS lookups:
One in BspService:
this.hostname = conf.getLocalHostname();
Another one is probably related:
java.net.UnknownHostException: ***.com: unknown error
