Enis Soztutar commented on HBASE-12787:
---------------------------------------

Thanks Alicia. Sorry, you have to change the default in hbase-common/src/main/resources/hbase-default.xml
as well. That takes precedence over the one in code.

When Configuration. getDouble(String key, double defaultValue) is called, it will respond
from the value in hbase-site.xml first, if not found hbase-default.xml second. If both does
not contain it will default to the defaultValue passed.

There are two 0.98-specific changes that should be addressed:
> # The default configuration should preserve current behavior
> # The interface change to RpcSchedulerFactory should be binary compatible for Phoenix
if possible, and we can do this by detecting with reflection if an older implementation of
the interface is missing the new 'create' method and by invoking the older deprecated 'create'
method instead. We can cache the decision after making it once.
