Debug Message "Received report from unknown server" should be INFO or WARN
--------------------------------------------------------------------------
Key: HBASE-2385
URL: https://issues.apache.org/jira/browse/HBASE-2385
Project: Hadoop HBase
Issue Type: Improvement
Components: master
Affects Versions: 0.20.3
Environment: Debian 6 / DNS with default mdns4
Reporter: Al Lias
Priority: Minor
We had debian 6 installed with a HA-DNS that failed-over.
As a result, the DNS resolution was wrong for a short moment and the master
received suddenly messages from "unknown" region servers:
2010-03-29 12:02:56,672 DEBUG org.apache.hadoop.hbase.master.ServerManager:
Received report from unknown server -- telling it to MSG_CALL_SERVER_STARTUP:
172.17.0.102,60020,1269856690485
This happened in production mode: I think, it relativly critical thing that
happened, so a INFO or WARN logging level would have helped us much quicker to
figure out the reason.
