            Description

            Currently query history stored in the memory of TajoMaster or QueryMaster. Query detail information is disappeared when the cluster is restarted. And because of memory limitations, only a few hours or a few days histories are kept.
            I suggest the following features for the query history.

            • Worker saves a query task history to the HDFS after finishing a query.
            • QueryMaster saves a query history to the HDFS after finishing a query.
            • If query is finished, Information Web server in TajoMaster shows query history in the web page, If query is running TajoMaster forward to QueryMaster.
            • History data will be saved to HDFS with JSON format.
            • JSON format has history file version for backward compatibility.
