Hi, I'm in the process of upgrading a few CDH3 clusters from 0.90.2 to 0.90.4. I noticed that after starting the 0.90.4 Master (also verified in 0.90.3), I see this series of messages every 5 seconds in the Master log: http://pastebin.com/TKeDiT9z
There are corresponding log entries in the ZooKeeper server log every 5 seconds: http://pastebin.com/N7VGMSFi So the Master is connecting to ZooKeeper and then immediately disconnecting every 5 seconds for some reason. Is this expected? I don't see any errors on the master or region servers, and HBase appears to be functioning normally. Should I just set the log level to WARN and not worry about it, or is this actually a problem? Thanks, James
