James Taylor commented on PHOENIX-2025:
---------------------------------------

FYI, [~mujtabachohan] - this may help our unit tests complete again on the 1.0 
and 1.1 branches 

> Phoenix-core's hbase-default.xml prevents HBaseTestingUtility from starting 
> up in client apps

> 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.
