Hey all, I'm seeing an issue where IPC Handlers aren't showing up in the Region server Web UI, even though jstack shows that they are waiting/processing. This is on Hbase 0.94.15-cdh4.7.0
For example, when it's working, it looks something like this: https://gist.github.com/bbeaudreault/aa72cf59e4d65d7ea385 And when it's not working it just looks like this: https://gist.github.com/bbeaudreault/02d6186ee95ef6dacfe9 Note that it's not an issue with the JSON interface, the HTML version doesn't show tasks either. However, compactions DO show up in the interface, so it's possible it is some difference in how MonitoredRPCHandlerImpl and MonitoredTaskImpl work. Restarting does fix the issue, but it returns after a while. Does anybody know what might be happening here? Thanks!
