Subject [jira] [Commented] (ACCUMULO-730) Run MR tests using local job tracker
Date Tue, 15 Jan 2013 21:26:17 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13554372#comment-13554372

Billie Rinaldi commented on ACCUMULO-730:
-----------------------------------------

Question: do we need to maintain compatibility with hadoop 0.20.205.0?  I'm about to check
in a patch for ACCUMULO-730.  I decided to use the plain local job tracker with MockAccumulo
(instead of MiniAccumuloCluster) since it's a bit more straightforward and we haven't planned
to deprecate MockAccumulo yet.  Either way involves adding a couple of dependencies to the
poms to get it to work for all of 1.0, 1.1, 0.23, and 2.0.  The only one added to the top-level
pom is commons-httpclient, which seems fine.  To get it to work for 0.20.205.0 as well, we
would have to add a dependency on jackson.  I'm reluctant to do so, but if someone needs 0.20.205.0,
I will.

> This can be done by setting the following properties, then calling ToolRunner.run.
> conf.set("mapred.job.tracker", "local");
> conf.set("fs.default.name", "file:///");
> If it doesn't take too much longer to run this way in a junit test, it would be preferable
to the manual context creation that is currently being done.
