The following page has been changed by udanax: http://wiki.apache.org/lucene-hadoop/Hbase/ShellPlans ------------------------------------------------------------------------------ = Hbase Shell Plan Draft = Plan is to significantly expand the set of shell operators. Basic data manipulation and data definition operators will be extended and evolved to be more SQL-like ([wiki:Hbase/HbaseShell/HQL HQL]). More sophisticated manipulations to do relational and linear algebra, matrix additions, multiplications, etc., will be added to a HBase subshell to keep the two operator types -- SQL-like vs. non-SQL -- distinct. - ''-- After POC(proof of concept) review, many things can change.'' + ''-- After POC(proof of concept) review, many things can change.[[BR]]-- If you have constructive ideas, Please advise me.
