Subject [jira] [Comment Edited] (HDFS-9427) HDFS should not default to ephemeral ports
Date Sat, 14 Nov 2015 00:54:11 GMT

-------------------------------------------------------------------

This issue has been a pet peeve of mine for years.  But every time this topic comes up, someone
complains that this makes testing on a single node hard.  I really, really, really hope we're
over that hump and we can not only remove the default of being ephemeral but also set the
ports to be a contiguous range.

> HDFS defaults to ephemeral ports for the some HTTP/RPC endpoints. This can cause bind
exceptions on service startup if the port is in use.
