HanCheol Cho commented on SENTRY-911:
-------------------------------------

Thank you for your reply to my question in Sentry mailing list.
I am adding this comment for a note.

sentry.hdfs.integration.path.prefixes property (for both sentry-site.xml and 
hive-site.xml) is necessary for non-default hive warehouse setting.
The default value is "/user/hive/warehouse".
Without this property set properly, Sentry-HDFS ACL synchronization will be 
disabled several hours later (probably timeout?).

The original information is from:
https://community.cloudera.com/t5/Cloudera-Manager-Installation/CDH-5-4-and-HDFS-Sentry-Plugin-Sync/td-p/28991

> Improve documentation on configuration and usage of HDFS ACL sync
