Brandon Li updated HDFS-3313:

    Attachment: HDFS-3313.HDFS-3092.patch

{quote}We should not change NameNodeProxies. NN is not involved in journal synchronization.{quote}
fixed by creating a static method in JournalService to get the roc proxy. 
{quote}For the same reason, the principals in JournalSyncProtocolPB should not be Namenode.{quote}
Replaced with Journal User Name
{quote}Use FSEditLog.getEditLogManifest(long fromTxId) instead of FileJournalManager and don't
change FileJournalManager.{quote}
{quote}Why DN is related to JournalSyncProtocol? Please check the comments.{quote}
{quote}I think we should pass JournalInfo in getEditLogManifest(..) so that it could first
verify the version, namespace id, etc.{quote}
{quote}Why the test is commented out?{quote}

> This protocol is used to synchronize lagging journal service with active journal service
with complete finalized edit segments. Currently it supports one rpc call getEditLogManifest()
which lists finalized edit segments.
