edward yoon commented on HADOOP-1608:
-------------------------------------
My suggestion is to develop HBase Shell in SQL-style, and develop numeric tools
as a sub shell as described below.
If you are okay with it, I want the development to start.
{code}
HBase > help;
Type 'help <command>;' to see command-specific usage.
CLEAR Clear the screen.
CREATE Create a table.
DELETE Delete cell or row in table.
DESCRIBE Describe a table's columnfamilies.
DROP Drop columnfamilie(s) from a table or drop table(s).
EXIT Exit shell
INSERT Insert row into table.
SELECT Select values from a table.
SHOW List all tables or files.
NUMERIC HBase Numeric Analyzer Tool.
HBase > numeric;
Hbase Numeric Shell, 0.0.1 version
Type 'help;' for Hbase Numeric Analyzer Tool usage.
HBase Numeric > help;
Type 'help <command>;' to see command-specific usage.
STORE Store results to specified table(or file).
SUBSTITUTE Substitute expression to [A~Z].
TABLE Load a table.
Relational Algebra Operators.
PROJECTION Make a new relation set {cf_name1, ... , cf_name2}.
SELECTION Make a new relation set of specified Rows.
SORT Make a new sorted set, ordered according to columnfamilies.
HBase Numeric > exit;
HBase > exit;
