Mark Robert Miller created HBASE-23796:
------------------------------------------
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.
