Subject [jira] Commented: (HADOOP-1720) [HbaseShell] Addition of HQL (Hbase Query Language) support in Hbase Shell
Date Wed, 12 Sep 2007 03:35:32 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1720?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12526663
] 

Edward Yoon commented on HADOOP-1720:
-------------------------------------

>>> ConsoleTable is also broken if column names or row names are longer than the
20 characters but I do not see this as a blocker (and I think Izaak is going to make a patch
for ConsoleTable tomorrow that should help in this regard).

>>> This v21 does a little cleanup and adds unit tests for create, describe, drop,
insert, etc. The create, etc., test is commented out currently. The test testInsertSelectDelete
currently fails because it tries to wrap row name in an insert in double quotes. It'll start
to pass when you fix the above issue. Feel free to add others (smile).


Thank you, Stack.

I appreciate your contribution and your code has been very helpful 
and it's been helping me learn a great deal about how to code better.

> We have defined the HQL (Hbase Query Language), which is a "more" SQL-like query language
for Hbase, for use in Hbase Shell. HQL is not intended to fully support the SQL syntax and
semantics. HQL, instead, is developed to make it easy to manipulate tables in Hbase through
the Hbase Shell command line, without using programming APIs.
> You can find more information about HQL in http://wiki.apache.org/lucene-hadoop/Hbase/HbaseShell/HQL.
