Thanks to Sameer Tiwari for doing initial code review, and valuable suggestions. The initial HBase-based implementation of namespace is not included in this patch. (Also, we did an implementation of current FSNameSystem, but hosted it in a separate JVM. That is also not included in this patch.) > Make Namespace implementation pluggable in the namenode > ------------------------------------------------------- > > Key: HDFS-5324 > URL: https://issues.apache.org/jira/browse/HDFS-5324 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode > Affects Versions: 2.1.1-beta > Environment: All > Reporter: Milind Bhandarkar > Assignee: Milind Bhandarkar > Fix For: 3.0.0 > > Attachments: AbstractNamesystem.java, Checklist Of Changes.docx, trunk_1544305_12-12-13.patch > > > For the last couple of months, we have been working on making Namespace > implementation in the namenode pluggable.
