Hi Prabath/Gokul, According to hadoop documentation there doesn't seem to be any major difference between the two releases [1] & [2]. However, 2.5.2 seems to have fixed some critical issues of 2.5.1 [3] (which are not directly mentioned), which is obviously carried out to 2.6.0. Since the datanode carbonization is done on 2.5.1 code, I am not sure how feasible it is to change it to 2.6.0, there seems to be improvements done on datanode code in this release. Since we have a release in 2 weeks time, and me and Deep are both working on tasks for this release, we could get someone from the team to check the feasibility of moving to 2.6.0. WDYT?
