Subject [jira] [Commented] (HBASE-7928) Scanning .META. with startRow and/or stopRow is not giving proper results
Date Tue, 26 Feb 2013 06:40:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7928?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13586856#comment-13586856
] 

stack commented on HBASE-7928:
------------------------------

In shell, could you just add the above constants when you notice it is .META. table and it
has startrow arg?  Ugly but user wouldn't see it.   Or you could just throw exception warning
user they need to add ',,' at least to make it work on .META. -- ugly but less surprising.

> This code will not return any result even if there is 10 tables with names starting with
"d" to "w", including one table called "entry". If you comment the setStopRow you will get
results, but will still get rows starting with "d" even if setStartRow is set to "e".
> Same code using with a user table is working fine.
> Facing the same issue with the shell.
> scan '.META.' , {STARTROW => 'e', LIMIT => 10} is returning rows starting by "d".
> scan '.META.' , {STARTROW => 'e', STOPROW => 'v', LIMIT => 10} is not returning
anything.
