Hi , I tried a quick smoke test build to see if I can build a Mahout binary that supports Spark 2.2.0
After a quick test I had some errors .. I will continue to debug, but posting here to see if anyone has some hints to help me get past this ... pom.xml modification (added) --> <profile> <id>spark-2.2</id> <activation> <property><name>spark-2.2</name></property> </activation> <properties> <spark.version>2.2.0</spark.version> <spark.compat.version>2.2</spark.compat.version> </properties> </profile> *Build command ...* mvn clean install -Phadoop2 -Pspark-2.2 *result snippet * a bunch of these type errors org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 17.0 failed 1 times, most recent failure: Lost task 0.0 in stage 17.0 (TID 55, localhost, executor driver): java.lang.NoSuchMethodError: org.apache.hadoop.fs.FileSystem$Statistics.getThreadStatistics()Lorg/ apache/hadoop/fs/FileSystem$Statistics$StatisticsData; at org.apache.spark.deploy.SparkHadoopUtil$$anonfun$3. apply(SparkHadoopUtil.scala:180) *** 19 TESTS FAILED *** [INFO] ------------------------------------------------------------ ------------ [INFO] Reactor Summary: [INFO] [INFO] Mahout Build Tools .................................
