Subject [jira] [Commented] (HDFS-3313) create a protocol for journal service synchronziation
Date Tue, 24 Apr 2012 20:39:06 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3313?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13260992#comment-13260992

Aaron T. Myers commented on HDFS-3313:

Seems like this patch duplicates a lot of code from NamenodeProtocol#getEditLogManifest and
related translators. Can this perhaps be factored out into a generic RemoteEditLogProtocol
that both the NN and journal service implement?

> 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.
