Nik Everett 12923ef896 Close and flush refresh listeners on shard close ... Right now closing a shard looks like it strands refresh listeners, causing tests like `delete/50_refresh/refresh=wait_for waits until changes are visible in search` to fail. Here is a build that fails: https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+multi_cluster_search+multijob-darwin-compatibility/4/console This attempts to fix the problem by implements `Closeable` on `RefreshListeners` and rejecting listeners when closed. More importantly the act of closing the instance flushes all pending listeners so we shouldn't have any stranded listeners on close. Because it was needed for testing, this also adds the number of pending listeners to the `CommonStats` object and all API to which that flows: `_cat/nodes`, `_cat/indices`, `_cat/shards`, and `_nodes/stats`.		2017-01-06 20:03:32 -05:00
