Subject [jira] Commented: (HADOOP-2047) [hbase] Add an '--master=X' and '--html' command-line parameters to shell
Date Tue, 11 Dec 2007 14:33:43 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12550456

stack commented on HADOOP-2047:

Your understanding above is correct. 

The '--master=MASTERHOST:PORT' makes it so you can have the shell connect to a cluster w/o
having to edit conf files; not that important but would be a nice to have.  The --html is
even less important but specifies that the output be in (x)html (See the mysql command.  It
takes formatting args including no formatting).

Take a look at Tool, ToolRunner and GenericOptionsParser in hadoop.  You might want to have
Shell implement Tool so you get your command-line processing done for you.  You be the judge
of whether its a good idea or not (On the one hand, you don't have to do anything and you
get specification of alternate conf file and handlign of -D for free but on the other, the
'-jt' and '-fs' are inapplicable in your context).

> Add to hbase shell command-line processing.  At a minimum should be able to pass the
master you want the shell to go against.  Currently you need to edit the hbase-site.xml that
is under the shell.   Also, add an '--html' to output resultsets in html rather than as ascii
tables (The html output is xhtml which might be sufficent for those who might want resultsets
as xml -- lets see).
