Hi, I created some unit tests to test some of the functions in my project which use Spark. However, when I used the sbt tool to build it and then ran the "sbt test", I ran into "java.io.IOException: Could not create FileClient":
2015-01-19 08:50:38,1894 ERROR Client fs/client/fileclient/cc/client.cc:385 Thread: -2 Failed to initialize client for cluster 127.0.0.1:7222, error Unknown error(108) num lines: 21 [info] TextFileAdapterTestSuite: [info] - Checking the RDD Vector Length *** FAILED *** [info] java.io.IOException: Could not create FileClient [info] at com.mapr.fs.MapRFileSystem.lookupClient(MapRFileSystem.java:351) [info] at com.mapr.fs.MapRFileSystem.lookupClient(MapRFileSystem.java:363) [info] at com.mapr.fs.MapRFileSystem.getMapRFileStatus(MapRFileSystem.java:795) [info] at com.mapr.fs.MapRFileSystem.getFileStatus(MapRFileSystem.java:822) [info] at org.apache.hadoop.fs.FileSystem.getFileStatus(FileSystem.java:1419) [info] at org.apache.hadoop.fs.FileSystem.globStatusInternal(FileSystem.java:1092) [info] at org.apache.hadoop.fs.FileSystem.globStatus(FileSystem.java:1031) [info] at org.apache.hadoop.mapred.FileInputFormat.listStatus(FileInputFormat.java:231) [info] at org.apache.hadoop.mapred.FileInputFormat.getSplits(FileInputFormat.java:277) [info] at org.apache.spark.rdd.HadoopRDD.getPartitions(HadoopRDD.scala:199) [info] ... The only tests failed, which I believe led to this exception are the ones where my functions call the SparkContext's function textFile(). I tried to debug this, and found that the exception seems to take place within the textFile() function. Does anybody know what is the issue and how to fix it? I used the local host for the SparkContext, does it have anything to do with this exception. Thanks, Jianguo
