Subject [jira] [Commented] (HDFS-234) Integration with BookKeeper logging system
Date Fri, 09 Dec 2011 22:11:40 GMT

    [ https://issues.apache.org/jira/browse/HDFS-234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13166616#comment-13166616

Jitendra Nath Pandey commented on HDFS-234:
-------------------------------------------

I think we should commit it to hdfs contrib. Please move the bkjournal package to contrib.

For secure hadoop setup, it will be important to have authenticated connection to book keeper
servers. That should be addressed in follow up jiras.

> BookKeeper is a system to reliably log streams of records (https://issues.apache.org/jira/browse/ZOOKEEPER-276).
The NameNode is a natural target for such a system for being the metadata repository of the
entire file system for HDFS.
