Subject Re: error starting MRAppmaster caused by java.lang.ClassNotFoundException: org.apache.hadoop.conf.Configuration$DeprecationDelta
Date Fri, 20 Nov 2015 05:54:02 GMT
The SimpleShortestPathsComputation example worked after I build Giraph
with  mvn -Phadoop_2 -Dhadoop.version=2.5.1 -DskipTests compile -X
I tried with hadoop 2.20 and also tried changing pom by adding a profile
for hadoop 2.2.0 in that and then tried building graph. But I was getting
sasl/jetty error. So finally i treid compiling it with  hadoop 2.5.1
version and it worked.
mvn -Phadoop_2 -Dhadoop.version=2.5.1 -DskipTests compile -X
