Hadoop 2.7 クラスターに Spark 1.4.1 をインストールしています。
エラーなしで SparkR シェルを開始しました。
bin/sparkR --master yarn-clientエラーなしで R コマンドを実行しました (spark.apache.org の紹介例):
df <- createDataFrame(sqlContext, faithful)コマンドを実行すると：
head(select(df, df$eruptions))
executor ノードで 15/09/02 10:08:29 に次のエラーが発生します。
「Rscript実行エラー: そのようなファイルまたはディレクトリはありません」.
どんなヒントでも大歓迎です。SparkR 以外の Spark タスクは、YARN クラスターで正常に実行されます。R 3.2.1 がインストールされ、ドライバー ノードで正常に動作します。
