Ashish Singhi commented on HBASE-16119:
---------------------------------------
bq. Adds a method to Admin. Is this an incompat change? Allowed but should we
tick the incompat box?
In master branch we will be supporting only java8 for now, so we can add
default methods in the interface and avoid the binary incompatibility.
