Subject Are Giraph Stats written in log only using map-reduce (hadoop2 mvn profile) ?
Date Sat, 08 Sep 2018 15:54:00 GMT
It seems that Giraph Stas are written in log only using map-reduce (
giraph-1.3.0-snapshot built with -Phadoop2 mvn profile). Follows an example
of Giraph Stats.

Is there a way to write Giraph Stats in logs using yarn too
(giraph-1.3.0-snapshot built with -Phadoop_yarn mvn profile) ?
