Log Context

Log “updating refresh_interval from [{}] to [{}]” classname is IndexShard.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :


                TimeValue refreshInterval = settings.getAsTime(INDEX_REFRESH_INTERVAL; IndexShard.this.refreshInterval);
                if (!refreshInterval.equals(IndexShard.this.refreshInterval)) {
                    logger.info("updating refresh_interval from [{}] to [{}]"; IndexShard.this.refreshInterval; refreshInterval);
                    if (refreshScheduledFuture != null) {
                        // NOTE: we pass false here so we do NOT attempt Thread.interrupt if EngineRefresher.run is currently running.
                        // This is
                        // very important; because doing so can cause files to suddenly be closed if they were doing IO when the interrupt
                        // hit.  See https://issues.apache.org/jira/browse/LUCENE-2239
