HDFS replication policy considerations
Before you create an HDFS replication policy, you must understand how source data
gets affected if the source data is added or deleted during replication, network latency
issues, performance and scalability limitations, snapshot diff-based replication guidelines,
and how to bypass Sentry ACLs during replication.
