java.io.FileNotFoundException: File does not exist: Error while
running Decision Tree Hadoop MapReduce
I am trying to run Decision Tree in Hadoop MapReduce.
But it is showing java.io.FileNotFoundException: File does not exist: in
cluster. But when i tried it from Eclipse it is showing the correct result
with the below settings
Configuration conf = new Configuration();
conf.set("fs.defaultFS", "remotesystem-ip/");
conf.set("hadoop.job.ugi", "hdfs");
And it created all the intermediate files under /user/sree/C45
hadoop fs -ls /user/sree/C45

Re: java.io.FileNotFoundException: File does not exist: Error while
running Decision Tree Hadoop MapReduce
Posted by unmesha sreeveni <un...@gmail.com>.
res = ToolRunner.run(new Configuration(), new C45(), args);
whether this can be the reason ..in eclipse i am getting the expected
output and a false result in cluster
I read that there are limitations in LocalJobRunner.

Re: java.io.FileNotFoundException: File does not exist: Error while
running Decision Tree Hadoop MapReduce
Posted by unmesha sreeveni <un...@gmail.com>.
Yes i copied my input file as -copyFromLocal
But the java.io.FileNotFoundException: File does not exist:
/user/sree/C45/intermediate1.txt is happenning as part of my Reduce function
C45 id=new C45();
System.out.println("count "+cnt);
Path input = new Path("C45/intermediate"+id.current_index+".txt");
//Path chck = new Path("C45/cnt_"+id.current_index+".txt");
Configuration conf = new Configuration();
conf.set("fs.defaultFS", "hdfs://my remote-ip/");
conf.set("hadoop.job.ugi", "hdfs");
FileSystem fs = FileSystem.get(conf);
BufferedWriter bw = new BufferedWriter(
new OutputStreamWriter(fs.create(input, true)));
System.out.println("Text from Reducer: "+
"C45/intermediate"+id.current_index+".txt"+ text);
System.out.println("file
exists:/user/dataadmin/C45/intermediate"+id.current_index+".txt"+fs.exists(input));
for(String str: text) {
bw.write(str);
}
bw.newLine();
bw.close();
As part of this code
Several intermediate files are created:
C45/intermediate0.txt
C45/intermediate1.txt
C45/intermediate2.txt
C45/intermediate3.txt
C45/intermediate4.txt
C45/intermediate5.txt
C45/intermediate6.txt
C45/intermediate7.txt
C45/rule.txt
I tried it from Eclipse
giving
Configuration conf = new Configuration();
conf.set("fs.defaultFS", "hdfs://my remote-ip/");
conf.set("hadoop.job.ugi", "hdfs");
FileSystem fs = FileSystem.get(conf);
My decision tree is successfull
But wen i export my program as jar file and run in cluster the above error
is happenening
But 2 files are created
C45/intermediate0.txt and C45/rule.txt.....
But this results in a wrong output.

Re: java.io.FileNotFoundException: File does not exist: Error while
running Decision Tree Hadoop MapReduce
Posted by unmesha sreeveni <un...@gmail.com>.
Yes i copied my input file as -copyFromLocal
But the java.io.FileNotFoundException: File does not exist:
/user/sree/C45/intermediate1.txt is happenning as part of my Reduce function
C45 id=new C45();
System.out.println("count "+cnt);
Path input = new Path("C45/intermediate"+id.current_index+".txt");
//Path chck = new Path("C45/cnt_"+id.current_index+".txt");
Configuration conf = new Configuration();
conf.set("fs.defaultFS", "hdfs://my remote-ip/");
conf.set("hadoop.job.ugi", "hdfs");
FileSystem fs = FileSystem.get(conf);
BufferedWriter bw = new BufferedWriter(
new OutputStreamWriter(fs.create(input, true)));
System.out.println("Text from Reducer: "+
"C45/intermediate"+id.current_index+".txt"+ text);
System.out.println("file
exists:/user/dataadmin/C45/intermediate"+id.current_index+".txt"+fs.exists(input));
for(String str: text) {
bw.write(str);
}
bw.newLine();
bw.close();
As part of this code
Several intermediate files are created:
C45/intermediate0.txt
C45/intermediate1.txt
C45/intermediate2.txt
C45/intermediate3.txt
C45/intermediate4.txt
C45/intermediate5.txt
C45/intermediate6.txt
C45/intermediate7.txt
C45/rule.txt
I tried it from Eclipse
giving
Configuration conf = new Configuration();
conf.set("fs.defaultFS", "hdfs://my remote-ip/");
conf.set("hadoop.job.ugi", "hdfs");
FileSystem fs = FileSystem.get(conf);
My decision tree is successfull
But wen i export my program as jar file and run in cluster the above error
is happenening
But 2 files are created
C45/intermediate0.txt and C45/rule.txt.....
But this results in a wrong output.
