Since the intensive load data in hive, our user prefer to use some tricky that using hdfs mv command to load their data into hive table instead of using load data hive command. The HDFS sentry-sync will force to change the ACL of the file to the setting we set on the sentry. This trick seems to work on speed up the loading data to hive.
My problem is that does this tricky make some side effect?
