> 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.
