    Description

      As mentioned in the design doc in HDFS-12943, to ensure consistent read, we need to introduce an RPC call msync. Specifically, client can issue a msync call to Observer node along with a transactionID. The msync will only return when the Observer's transactionID has caught up to the given ID. This JIRA is to add this API.
