Major compactions can take long time depending on data size. Are you moving from an earlier version of HBase to 2.1.4 i.e. did this loading process work fine earlier? When you mentioned "200 puts as a batch in a java thread" assuming you are using HBase batch mutation? How much memory out of the 64 GB allocated to HBase? Any frequent long GC pauses (information should be available in the RS GC logs)? If you are loading a fresh table is it pre-split to take advantage of all the RSes you have? Any other workload during this data load?
