But in case of big*big join does > not process well. > Therefore Need other method like Hive. > I implemented hive-phoenix-handler that can access Apache Phoenix table on > HBase using HiveQL. > hive-phoenix-handler is very faster than hive-hbase-handler because of > applying predicate push down. > I am publishing source code to github for contribution and maybe will be > completed by next week. > https://github.com/mini666/hive-phoenix-handler > please, review my proposal. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
