Sean Owen commented on SPARK-4360: ---------------------------------- I don't think there's enough info here; this maybe should have been a question on the list first. Is there more than 1 partition in the input? did more than 1 executor actually allocate? are you definitely observing tasks running and not some single-threaded process on the driver? > task only execute on one node when spark on yarn > ------------------------------------------------ > > Key: SPARK-4360 > URL: https://issues.apache.org/jira/browse/SPARK-4360 > Project: Spark > Issue Type: Bug > Affects Versions: 1.0.2 > Reporter: seekerak > > hadoop version: hadoop 2.0.3-alpha > spark version: 1.0.2 > when i run spark jobs on yarn, i found all the task only run on one node, my > cluster has 4 nodes, executors has 3, but only one has task, the others > hasn't, my command like this : > /opt/hadoopcluster/spark-1.0.2-bin-hadoop2/bin/spark-submit --class > org.sr.scala.Spark_LineCount_G0 --executor-memory 2G --num-executors 12 > --master yarn-cluster /home/Spark_G0.jar /data /output/ou_1 > is there any one knows why? -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
