dfsioe YARN error while generating Input Data about hibench

[adrian-wang]

Did you have your HDFS working, and have right privileges?

[manishagajbe]

I don't have a standard HDFS. I am using Lustre. I am able to run the TestDFSIO benchmark that comes along with Hadoop distribution.

[adrian-wang]

What do you mean by myHadoop and Hadoop?

[manishagajbe]

myHadoop : myHadoop provides a framework for launching Hadoop clusters within traditional high-performance compute clusters and supercomputers. It allows users to provision and deploy Hadoop clusters within the batch scheduling environment of such systems with minimal expertise required.

Hadoop : the opensource Apache Hadoop

I am able to run the simple wordcount, pi and TestDFSIO too. Are there any parameters that I can pass using "-D" to DFSIOE to force it using the base directory? For some reason, the "-Dtest.build.data= .... ", doesn't seem to work when I run the example. I use this option with "TestDFSIO", and it works just fine. I even tried using explicit path in the run script that is in HiBench distribution.

I have similar problems with "Nutchindexing" and "Bayesian" where the default file to read from is "/usr/share/dict/linux.word" and I don;t have that file but I do have "/usr/share/dict/american". Is there a way to change the files to read from?

[adrian-wang]

TestDFSIOEnh may not support that argument.

for the dictionary file, you could make a soft link as a workaround.

[hasonhai]

Got the same issue. I'm using HDP 2.1 and Ambari 2.0.0.
DFSIOEnh fail to run this command to create the data input for test:

${HADOOP_EXECUTABLE} jar ${DATATOOLS} org.apache.hadoop.fs.dfsioe.TestDFSIOEnh \
    -Dmapreduce.map.java.opts="-Dtest.build.data=${INPUT_HDFS} $MAP_JAVA_OPTS" \
    -Dmapreduce.reduce.java.opts="-Dtest.build.data=${INPUT_HDFS} $RED_JAVA_OPTS" \
    -write -skipAnalyze -nrFiles ${RD_NUM_OF_FILES} -fileSize ${RD_FILE_SIZE} -bufferSize 4096 

The job was received by Yarn but then job failed and containers were killed.

I have created a soft link for linux.words file, however I do see the error
"ERROR: number of words should be greater than 0"
The linux.words file is not empty.

We have been seeing the same issue as @hasonhai with Hortonworks HDP 2. I found the issue after debugging and tested a fix. I can send a Pull request, if you are interested.

[manishagajbe]

Sure. Thanks.

I have sent a pull request ( #110 ) to fix the issue with using wrong FS resulting in errors like "Mkdirs failed to create" etc. Please take a look and merge so that people who run into this issue (e.g. using Hortonworks HDP 2) will benefit.
