-----------------------------
Summary: HMSFollower keep getting full snapshot when HDFS is
disabled
Key: SENTRY-1890
URL: https://issues.apache.org/jira/browse/SENTRY-1890
Project: Sentry
Issue Type: Bug
Components: Sentry
Affects Versions: 2.0.0
Reporter: Na Li
Assignee: Na Li
Priority: Critical
Sergio found that when HDFS sync is disabled, full snapshot is not persisted
into data store. However, when data store is empty, we decide to get full
snapshot. Therefore, every run, we get full snapshot from HMS. This causes big
overhead.
The solution is to check if the notification ID table is empty or not because
even when HDFS sync is disabled, we still persist the notification ID into
notification ID table.
