# Netty is shaded in hbase. The shaded netty is pulled in with org.apache.hbase.thirdparty:hbase-shaded-netty.

# It has a .so in it. Shading requires rename of the .so and then passing a system property so netty finds the

# renamed .so and associates it w/ the relocated netty files.
|

# So we can find the relocated .so, we need to add a system property pointing at new location. Trick is from:
