----------------------------------------
Summary: monitor service GET / hangs if Zookeeper down
Key: ACCUMULO-1723
URL: https://issues.apache.org/jira/browse/ACCUMULO-1723
Project: Accumulo
Issue Type: Bug
Components: monitor
Affects Versions: 1.6.0
Environment: small pseudo-cluster where the single-node ZK has been
shut down
Reporter: Steve Loughran
Priority: Minor
Once ZK is offline, you can't issue GET (or POST or HEAD, but not PUT) requests
against URLs on the monitors web port. The requests just hang. Invalid HTTP
requests get rejected by Jetty, so the process itself is running, it's just
whatever servlet is fielding requests is blocking without timeouts waiting for
ZK, or for a lock to be released by some other thread that is blocked on ZK.
While a ZK outage is not something you'd plan for in a real cluster, it is the
kind of thing you'd hope the monitor to pick up and explicit highlight as a
problem -especially if the page is being fetched by a machine process rather
than an individual
