I've posted an hbase 0.20.4 release candidate 4 here: http://people.apache.org/~stack/hbase-0.20.4-candidate-3/
Should we release this candidate as hbase 0.20.4? It includes some critical fixes and some performance enhancements (See CHANGES.txt or the release notes in the docs [1] for issues addressed by this candidate). Please take it for a test spin if you have a chance. Vote closes Friday, the 30th of April. Yours, Your HBase Team 1. http://people.apache.org/~stack/hbase-0.20.4-candidate-4/hbase-0.20.4/docs/releasenotes.html
