Subject [jira] [Commented] (HBASE-7243) Test for creating a large number of regions
Date Tue, 11 Dec 2012 20:11:23 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13529294#comment-13529294

Nick Dimiduk commented on HBASE-7243:
-------------------------------------

Reducing this to a single regionserver with 1000 regions allows this test to execute within
the memory constrains already imposed by the hbase-it/pom.xml. It completes pretty consistently
in 150-200 secs on my laptop (no ramdisk).

Using the @Test(timeout=...) feature is appealing because it simplifies the test logic considerably.
However, only constant expressions are accepted as arguments to the @Test annotation. That
means this setting cannot be altered by a local administrator who is also interested in tweaking
the other values. For this reason, I'll retain the existing timer logic -- that is, unless
there's a strong desire to remove configurability in general from this patch.

> After HBASE-7220, I think it will be good to write a unit test/IT to create a large number
of regions. We can put a reasonable timeout to the test.
