As of SDP 24.7 we do include HBase 2.6 support in an experimental state.
HBase 2.6 support was added with PHOENIX-7172 and released with Phoenix 5.2.1, which is included since SDP 25.3. SDP 24.7 included Phoenix built from the master branch from commit 4afe457.
Repository: hbase-operator-tools
Built from git hash 7c738fc (master) since no release supporting HBase 2.6 available yet.
