JiangHua Zhu updated HDFS-16650: -------------------------------- Description: Getting timestamps in Centralized cache management is done in the following ways: long now = new Date().getTime(); This approach doesn't seem to be optimal since we only use it once here. It might be better to use the tool Time to get the timestamp. E.g: long now = Time.now(); was: Getting timestamps in Centralized cache management is done in the following ways: long now = new Date().getTime(); This approach doesn't seem to be optimal since we only use it once here.
