snapshotWorkingDir doesn't update in all situations #3353

Closed sascha-coenen closed 5 years ago

sascha-coenen commented 8 years ago

When removing a dynamic lookup spec by sending a "DELETE" action to the respective coordinator endpoint, the historicals update their lookupSnapshot.json snapshot accordingly.

However, when posting a complete lookup spec to the /druid/coordinator/v1/lookups endpoint, the lookupSnapshot.json files do not get updated. There are also no log statements contained in the historical logs that would indicate that updating the file wasn't successful. Posting updates to individual lookups also doesn't update the snapshot files.

BTW: sending DELETE or POST actions to the coordinator endpoints for a single lookup definition works in so far as it performs the action, but the REST calls hang. All other rest endpoints work for me and do not hang.

correction: the DELETE or POST actions do not actually hang. this was unrelated to Druid, but the snapshot files still only get updated in some situations.
