----------------------------------------
Summary: Phoenix-core's hbase-default.xml prevents
HBaseTestingUtility from starting up in client apps
Key: PHOENIX-2025
URL: https://issues.apache.org/jira/browse/PHOENIX-2025
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.3.0
Reporter: Geoffrey Jacoby
Phoenix seems to have long had its own version of hbase-default.xml as a test
resource in phoenix-core with a single setting to override
hbase.defaults.for.version.skip to true. Sometime around Phoenix 4.3,
phoenix-core seems to have been split into a main jar and a test jar, and the
hbase-default.xml went into the test jar.
The odd result of this is that in client apps that include the test jar, the
classloader in HBaseConfiguration.create() now sees Phoenix's
hbase-default.xml, rather than HBase's, and creates a Configuration object
without HBase's defaults. One major consequence of this is that the
HBaseTestingUtility can't start up, because it relies on those HBase defaults
being set. This is a huge problem in a client app that includes the
phoenix-core test jar in order to make use of the PhoenixTestDriver and
BaseTest classes; the upgrade to 4.3 breaks all tests using the
HBaseTestingUtility.
I've verified that phoenix-core's own tests don't pass if its internal
hbase-default.xml is missing (ZK has problems starting up), and that renaming
it to hbase-site.xml doesn't seem to fix the problem either. I looked around
for a central point in code to manually set the hbase.defaults.for.version.skip
flag, but couldn't find one; BaseTest didn't seem to cover all the needed test
cases.
