The latency of HBase might cause some performance issues if you have a lot of writes, especially of you use HBase for the Journal impl. A better alternative might be a PM based on Cassandra with knowledge of the "home" server for inconsistent storage bundles. Unfortunately this does not exist yet.

Can I use jackrabbit based on hadoop by deploying repository.xml .Just like the LocalFileSystem and DataBase as based structure. The PersistenceManager uses Hadoop HBase and The data store implementation uses plain Hadoop HDFS.
