Summary: Consider using 127.0.0.1 instead of localhost and binding to 127.0.0.1 as well. Key: HBASE-23796 URL: https://issues.apache.org/jira/browse/HBASE-23796 Project: HBase Issue Type: Test Reporter: Mark Robert Miller This is perhaps controversial, but there are a variety of problems with counting on dns hostname resolution, especially for locahost. # It can often be slow, slow under concurrency, or slow under specific conditions. # It can often not work at all - when on a VPN, with weird DNS hijacking hi-jinks, when you have a real hostname for you machines, a custom /etc/hosts file, OS's run their own local/funny DNS server services. # This makes coming to HBase for new devs a hit or miss experience and if you miss, dealing with an diagnosing the issues is a large endeavor and not straight forward or transparent. # 99% of the difference doesn't matter in most cases - except that 127.0.0.1 works and is fast pretty much universally. -- This message was sent by Atlassian Jira (v8.3.4#803005)
