---------------------------------------
Summary: TestingHBaseCluster should support running MapReduce jobs
Key: HBASE-26102
URL: https://issues.apache.org/jira/browse/HBASE-26102
Project: HBase
Issue Type: Test
Components: test
Affects Versions: 3.0.0-alpha-1
Reporter: Geoffrey Jacoby
The existing HBaseTestingUtility optionally allows users to start a mini-YARN
cluster for the purpose of running MapReduce jobs, such as testing applications
that use HBase's MapReduce integration.
The new TestingHBaseCluster is a cleaner interface than HBTU, but exposes less
functionality, and in particular does not seem to allow for starting a YARN
minicluster. This would make it difficult to use in some common circumstances,
such as testing Phoenix's index builds, which use MapReduce.
Many downstream projects that depend on HBase may also have batch logic done as
MapReduce or other kinds of YARN jobs.
