在Hadoop 2 namenode

上的Spark（0.9.1）shell中运行此示例 
scala> val file1 = sc.textFile("hdfs://testhadoopname1.myserver.com:9000/user/ubuntu/events/datepart=2014-04-11/2014-04-11-09-42.txt")

14/04/16 10:27:01 INFO storage.MemoryStore: ensureFreeSpace(74968) called with curMem=302142, maxMem=311387750
14/04/16 10:27:01 INFO storage.MemoryStore: Block broadcast_3 stored as values to memory (estimated size 73.2 KB, free 296.6 MB)
file1: org.apache.spark.rdd.RDD[String] = MappedRDD[7] at textFile at :12

scala> file1.count()

为什么我会这样做？

答案 0 :(得分：2)

问题是我使用的是Hadoop的不合格版本（2.0.3-alpha版本）。我使用Spark 0.9.1独立集群管理器在最新的Hadoop 2.3.0上重新创建了HDFS集群，并在spark-shell中运行了上述示例......就像宣传的那样。
