  4. Possible Issues

This benchmark suite contains 10 typical micro workloads. This benchmark suite also has options for users to enable input/output compression for most workloads with default compression codec (zlib). Some initial work based on this benchmark suite please refer to the included ICDE workshop paper (i.e., WISS10_conf_full_011.pdf).

Note:

1. Since HiBench-2.2, the input data of benchmarks are all automatically generated by their corresponding prepare scripts.
2. Since HiBench-3.0, it introduces Yarn support
3. Since HiBench-4.0, it consists of more workload implementations on both Hadoop MR and Spark. For Spark, three different APIs including Scala, Java, Python are supportive.

Micro benchmarks:

1. Sort (sort)

   This workload sorts its text input data, which is generated using RandomTextWriter.

2. WordCount (wordcount)

   This workload counts the occurrence of each word in the input data, which are generated using RandomTextWriter. It is representative of another typical class of real world MapReduce jobs - extracting a small amount of interesting data from large data set.

3. TeraSort (terasort)

   TeraSort is a standard benchmark created by Jim Gray. Its input data is generated by Hadoop TeraGen example program.

4. Sleep (sleep)

   This workload sleep an amount of seconds in each task to test framework scheduler.

SQL:

5. Scan (scan), Join(join), Aggregate(aggregation)

   This workload is developed based on SIGMOD 09 paper "A Comparison of Approaches to Large-Scale Data Analysis" and HIVE-396. It contains Hive queries (Aggregation and Join) performing the typical OLAP queries described in the paper. Its input is also automatically generated Web data with hyperlinks following the Zipfian distribution.

Web Search Benchmarks:

6. PageRank (pagerank)

   This workload benchmarks PageRank algorithm implemented in Spark-MLLib/Hadoop (a search engine ranking benchmark included in pegasus 2.0) examples. The data source is generated from Web data whose hyperlinks follow the Zipfian distribution.

7. Nutch indexing (nutchindexing)

   Large-scale search indexing is one of the most significant uses of MapReduce. This workload tests the indexing sub-system in Nutch, a popular open source (Apache project) search engine. The workload uses the automatically generated Web data whose hyperlinks and words both follow the Zipfian distribution with corresponding parameters. The dict used to generate the Web page texts is the default linux dict file /usr/share/dict/linux.words.

Machine Learning:

9. Bayesian Classification (bayes)

   This workload benchmarks NaiveBayesian Classification implemented in Spark-MLLib/Mahout examples.

   Large-scale machine learning is another important use of MapReduce. This workload tests the Naive Bayesian (a popular classification algorithm for knowledge discovery and data mining) trainer in Mahout 0.7, which is an open source (Apache project) machine learning library. The workload uses the automatically generated documents whose words follow the zipfian distribution. The dict used for text generation is also from the default linux file /usr/share/dict/linux.words.

10. K-means clustering (kmeans)

    This workload tests the K-means (a well-known clustering algorithm for knowledge discovery and data mining) clustering in Mahout 0.7/Spark-MLlib. The input data set is generated by GenKMeansDataset based on Uniform Distribution and Guassian Distribution.

HDFS Benchmarks:

10. enhanced DFSIO (dfsioe)

    Enhanced DFSIO tests the HDFS throughput of the Hadoop cluster by generating a large number of tasks performing writes and reads simultaneously. It measures the average I/O rate of each map task, the average throughput of each map task, and the aggregated throughput of HDFS cluster. Note: this benchmark doesn't have Spark corresponding implementation.

Supported hadoop/spark release:

• Apache release of Hadoop 1.x and Hadoop 2.x
• CDH4/CDH5 release of MR1 and MR2.

   Note: All spark.* properties will be passed to Spark runtime configuration.

2. Compress options:

      hibench.compress.profile              Compression option `enable` or `disable`
      hibench.compress.codec.profile        Compression codec, `snappy`, `lzo` or `default`
   

3. Data scale profile selection:

      hibench.scale.profile                 Data scale profile, `tiny`, `small`, `large`, `huge`, `gigantic`, `bigdata`
   

   You can add more data scale profiles in conf/10-data-scale-profile.conf. And please don't change conf/00-default-properties.conf if you have no confidence.

4. Configure for each workload or each language API:

   1. All configurations will be loaded in a nested folder structure:

        conf/*.conf                                         Configure globally
        workloads/<workload>/conf/*.conf                    Configure for each workload
        workloads/<workload>/<language APIs>/.../*.conf     Configure for various languages
      

   2. For configurations in same folder, the loading sequence will be sorted according to configure file name.

   3. Values in latter configure will override former.

   4. The final values for all properties will be stored in a single config file located at report/<workload><language APIs>/conf/<workload>.conf, which contain all values and pinpoint the source of the configures.

5. Configure for future Spark release

   By default, bin/build-all.sh will build HiBench for all running environments:

      - MR1, Spark1.2
      - MR1, Spark1.3
      - MR2, Spark1.2
      - MR2, Spark1.3
   

   And HiBench will probe Hadoop & Spark release version and choose proper HiBench release automatically. However, for furture Spark release (for example, Spark1.4) which is API compatibled with Spark1.3. HiBench'll fail due to lack the profile. You can define Hadoop/Spark release version by setting to force HiBench using Spark1.3 profile:

      hibench.spark.version          spark1.3
   

6. Configures for running workloads and language APIs:

The conf/benchmarks.lst file under the package folder defines the workloads to run when you execute the bin/run-all.sh script under the package folder. Each line in the list file specifies one workload. You can use # at the beginning of each line to skip the corresponding bench if necessary.

You can also run each workload separately. In general, there are 3 different files under one workload folder.

  prepare/prepare.sh            Generate input data in HDFS for
                                running the benchmark
  mapreduce/bin/run.sh          run MapReduce language API
  spark/java/bin/run.sh         run Spark/java language API
  spark/scala/bin/run.sh        run Spark/scala language API
  spark/python/bin/run.sh       run Spark/python language API

1. Running Spark/Python API with YARN:

   Due to SPARK-1703 and SPARK-1911, Oracle-JDK-1.6 is preferred.

2. Running with CDH/MR1:

   For a tarball deployed CDH/MR1, please recreate symlink file hadoop-*-cdh*/share/hadoop/mapreduce to point to correct folder:

      cd share/hadoop
      rm mapreduce
      ln -s mapreduce1 mapreduce
   

3. Running Spark/Python, MLLib related workloads:

   You'll need to install numpy (version > 1.4) in master & all slave nodes.

   For CentOS(6.2+):

   yum install numpy

   For Ubuntu/Debian:

   aptitude install python-numpy

4. Execute <HiBench_Root>/bin/report_gen_plot.py:

   You'll need to install python-matplotlib(version > 0.9).

   For CentOS(6.2+):

   yum install python-matplotlib

   For Ubuntu/Debian:

   aptitude install python-matplotlib
