Zhihong Ted Yu commented on HBASE-2315: --------------------------------------- The ctor of HLog takes a FileSystem parameter. Since the FileSystem isn't important to bookkeeper, my feeling is that the approach in previous patch makes sense. You can remodel that patch by introducing a new hbase module. Thanks > BookKeeper for write-ahead logging > ---------------------------------- > > Key: HBASE-2315 > URL: https://issues.apache.org/jira/browse/HBASE-2315 > Project: HBase > Issue Type: New Feature > Components: regionserver > Reporter: Flavio Junqueira > Attachments: HBASE-2315.patch, bookkeeperOverview.pdf, > zookeeper-dev-bookkeeper.jar > > > BookKeeper, a contrib of the ZooKeeper project, is a fault tolerant and high > throughput write-ahead logging service. This issue provides an implementation > of write-ahead logging for hbase using BookKeeper. Apart from expected > throughput improvements, BookKeeper also has stronger durability guarantees > compared to the implementation currently used by hbase. -- This message is automatically generated by JIRA.
