Subject [jira] [Commented] (ACCUMULO-2594) Improve TabletLocator.getInstance() to check tableId points to a table which exists
Date Tue, 07 Apr 2015 02:54:13 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2594?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14482484#comment-14482484
] 

Josh Elser commented on ACCUMULO-2594:
--------------------------------------

Are tableIds actually checked though? Despite the construction of a TabletLocator instance
changing, I don't recall seeing this sanity check being added. The way that a TabletLocator
is instantiated is unrelated to the original bug report.

> If you pass an invalid tableId (or in my case tableName instead of tableId) TabletLocator
won't complain.
> TabletLocator tabletLocator = TabletLocator.getInstance(instance, new Text(tableId));
> Next if you use the returned tabletLocator to locate a tablet it just returns an empty
list, never complaining that the tableId was invalid:
> TabletLocator.TabletLocation tabletLocation = tabletLocator.locateTablet(rowKey.getText(),
false, false, credentials.toThrift());
> Ideally TabletLocator.getInstance() should guard against invalid/non-existing tableIds.
