Subject [jira] [Commented] (HDFS-3186) Sync lagging journal service from the active journal service
Date Wed, 02 May 2012 22:26:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3186?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13266965#comment-13266965
] 

Suresh Srinivas commented on HDFS-3186:
---------------------------------------

Preliminary comments:
# JournalService.java
#* JournalSync conf should be renamed as it hides outer class conf.
#* Remove unnecessary casting 3 to long
#* In startLogSegment the comment you have added is unnecessary
#* Why do you want to throw IllegalStateException in inSync() method?
#* Update the JournalService constructor javadoc for newly added parameters
#* Why should syncThread be a never ending thread?
#* There are bunch of TODO items
#* Why would syncThread be not null in run() method?
#* Please use space after // in comments. Also for method comments use /** */ comments.
#* runSync - startSync name better? valueSet may not be needed?
#* enableRunSync() - startSync() better name?
#* getRunSync() - waitForStartSync() better name?
#* Add javadoc to JouranalSync methods
#* rename getAllJournalSegments to syncAllJournalSegments?
#* "Sync trial failed for" to "Sync failed for"
