updated to version 2.1.2
Fixed issue where NPE could be thrown by c.s.CascadingStats#getCounterValue if given counter had no value.
Fixed issue where fetching remote Hadoop counter values could block indefinitely. Fetching remote counters is now serialized across jobs to prevent deadlocks inside the Hadoop API and counter values are now cached with a final refresh on job completion.
updated copyright dates
Fixed issue where c.f.FlowProcess#openForWrite on Hadoop would re-use the existing o.a.h.m.OutputCollector instance as that used in the current task.
fix for non-daemon stats counters thread causing jvm hang
