------------------------------------
Summary: Move fixed server ports out of ephemeral port range
Key: ACCUMULO-3921
URL: https://issues.apache.org/jira/browse/ACCUMULO-3921
Project: Accumulo
Issue Type: Improvement
Components: gc, master, monitor, trace, tserver
Reporter: Josh Elser
Priority: Critical
Fix For: 1.8.0
During some recent testing, we ran into a case where the monitor failed to
restart. Looking at the logs after the fact (it was an automated test), the
monitor died because it couldn't bind to 50095.
The likely problem is that the datanode or namenode happened to grab that port
because it's in the ephemeral range which is commonly 32768-61000 (per
[wikipedia|https://en.wikipedia.org/wiki/Ephemeral_port]).
It would be good to give our ports a once-over and start to push towards better
default values. This has been a problem for us for quite some time.
