bq. the node existed but was in the state C_M_MODIFY_FAMILY set by the server xxx:60000
Can you check server log of xxx (and master log) ? Looks like column family modification was happening around the same time. BTW 0.90 was really old. There have been 0.92, 0.94, 0.96 and 0.98 releases. In fact 1.0.0 release is around the corner. Please consider upgrade.
