Our central git repository is down right now. See http://status.apache.org/.
Our mailing list might also be down at the moment, which might mean that by the time you get this message, everything is back up. There are unofficial mirrors at http://gerrit.cloudera.org:8080/Impala-ASF and https://github.com/apache/incubator-impala. These unofficial mirrors frequently lead or lag the official repo by a few commits.
