[Hawkular-dev] Titan 0.5.4 with Cassandra 3.3

[Peter Palaga]

Hi *,

Short version: I want to release our own fixed Titan 0.5.4-jboss-1 that 
works with Cassandra 3.3

Long version:

Titan is a graph database used by Hawkular Inventory. ATM, we use Titan 
0.5.4 with Cassandra 2.x.

As I already noted elsewhere, Titan 0.5.4 requires Guava 15 that is 
incompatible with Guava 18 required by the newest c* 3.x Driver. The 
conflict seems to be solved in the titan05 branch [1] in the 
thinkaurelius repo. I asked both their release engineer directly and on 
their mailing list [2] if they could release Titan 0.5.5, but got no 
reply so far. It does not look like we can hope for a release from them 
soon.

Therefore, I propose the following:
* I'll fork Titan code from their 0.5.4 tag
* I'll apply the changes necessary for Titan 0.5.4 to work with 
Cassandra 3.3
* I'll change the groupId from com.thinkaurelius.titan to org.hawkular.titan
* I'll release the result as Titan 0.5.4-jboss-1

This should be just a temporary solution till Inventory is migrated to 
Titan 1.0 API that should work with the newest Cassandra.

Are there any concerns about this proposal?
