Subject [jira] Commented: (HBASE-1175) HBA administrative tools do not work when specifying regionName
Date Tue, 03 Feb 2009 15:43:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1175?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12669994#action_12669994
] 

Jonathan Gray commented on HBASE-1175:
--------------------------------------

Andrew, will test today but this should not have broken the existing semantics.

Code in HMaster supports three possibilities now:  (null,regionName)  (tableName,rowKey) 
or (tableName,null)

Whether or not that's what we want is another question, but as this patch stands this is all
supported.  Not sure if we want to expose all three possibilities to web ui, HBA, shell.

> HBaseAdmin administrative functions allow tableName or regionName through the API.  Things
are okay if we pass tableName, but when using regionName the code in HMaster is incorrect.
 It is expecting to be passed tableName and startRow, but we are passing null and regionName.
 Patch will fix master to handle this case properly.
