Summary: Introduce msync API call
Key: HDFS-13688
URL: https://issues.apache.org/jira/browse/HDFS-13688
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Chen Liang
Assignee: Chen Liang
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.
