Shixiong Zhu 417e45c584 [SPARK-18796][SS] StreamingQueryManager should not block when starting a query ... ## What changes were proposed in this pull request? Major change in this PR: - Add `pendingQueryNames` and `pendingQueryIds` to track that are going to start but not yet put into `activeQueries` so that we don't need to hold a lock when starting a query. Minor changes: - Fix a potential NPE when the user sets `checkpointLocation` using SQLConf but doesn't specify a query name. - Add missing docs in `StreamingQueryListener` ## How was this patch tested?
