The 1.0.3 and 1.0.13 should be compatible. The API didn't change, at least for the part you guys are using.
We added bunch of new features, but ensuring we don't mess with backward compatibility.
The reason for not shipping Linux binaries is the fact that we switched to more secure libcap, and that lib can have different .so names across different Linux distros, so we cannot have a generic one. However many distros already provide daemon binaries, and for the ones that don't the build is simple 'configure && make install'.
Looking at the
I see couple of things that can be improved, but basically that's fine and will work with 1.0.13. In any case eventual fix would be trivial since you don't use singnaling (SIG_USR2) API inside SecureDataNodeStarter, and I'm ready to help you guys with that.
If you have have some nightly (or something like that) binaries I do a couple of smoke test and come up with eventual fixes.
Like said I'd suggest you upgrade to more recent versions mainly for security reasons and the fact that many linux distros already ship with contemporary versions.
