Subject [jira] [Commented] (HBASE-7938) Add integration test for various MapReduce workflows
Date Thu, 07 Mar 2013 21:21:11 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13596387#comment-13596387

Enis Soztutar commented on HBASE-7938:
--------------------------------------

bq. d like to modify IntegrationTestsDriver to accept any class that implements Tool. With
that change, I can modify the existing unit tests to implement a run method where the prickly
scenarios can be run against an external cluster, as configured by IntegrationTestsDriver
Having ITs being able to run from command line, or as an integration test or a unit test gives
us the most flexible approach. For example, recently added TestLoadAndVerify does have this.
How do you plan to have IntegrationTestsDriver discover these tests, and figure out the arguments?

> We have existing unit tests for smoke-testing the packaged MR jobs, however they do not
create a runtime environment that is true to running on a real MR cluster. This is particularly
true in regard to classpaths (HBASE-7934) but also other static state (HBASE-4802). An integration
test that can be pointed to run on a pseudo-distributed Hadoop deployed on localhost would
find these kinds of problems.
