HiBench 7.x 使用问题整理
一. 介绍
HiBench是一款用于hadoop集群性能测试的开源工具。支持MR,HIVE,SPARK等计算框架，且支持多种维度的测试。早在HiBench5.0的时候作者就用过，个人感觉还不错，无论是apache hadoop，cdh还是hdp都可以支持。
最新发现，HiBench 7.x 版本发布了。因此就趁着机会，结合新版本总结一下使用中遇到的问题，助大家过坑。
HiBench的github地址如下：https://github.com/intel-hadoop/HiBench
环境：
OS:CentOS 7.3
Hadoop: HDP 2.6.5.x
HiBench: 7.1
二. 安装
安装方式：
使用maven命令即可，具体请见：https://github.com/intel-hadoop/HiBench/blob/master/docs/build-hibench.md

问题原因：
网站访问协议更换导致的对应文件下载异常。
解决方法：
方式1. 将pom.xml中的"http"修改为"https"，例如：
https://archive.apache.org
dist/hive/hive-0.14.0/apache-hive-0.14.0-bin.tar.gz
方式2. 将对应文件在"https://archive.apache.org/dist"此源中下载至本地http，再修改pom.xml中的文件路径，例如：
http://private.repo.io/archive.apache.org
dist/hive/hive-0.14.0/apache-hive-0.14.0-bin.tar.gz
第一种方式最简单。如果网速不给力，请用第二种方法。
三. 使用
使用方式：
具体不同的测试请参见：https://github.com/intel-hadoop/HiBench/blob/master/docs/ 中的"run-*.md"

... 21 more问题原因：
HiBench在使用过程中，会需要在HDFS下建立目录，如果默认使用root用户进行测试，且HDFS开启简单权限模式的话（hdfs为超级用户），自然会权限限制。
解决方法：
预先创建以下目录，并修改权限（暴力点可以直接给777，或是确定进行测试用户具备相应目录的写权限）：
注：部分目录可通过conf/hibench.conf进行修改，以下目录参考是以默认配置文件为基准的。
/HiBench
/var
/user/root # root是作者用来测试的用户===================================================================
sparkbench 日志没有输出到job history的问题：
问题描述：
使用默认的HiBench的运行命令执行spark作业测试，例如：
bin/workloads/sql/scan/spark/run.sh该spark作业的日志将不会出现在job history server中。
问题原因：
HiBench的作业默认使用的是自生成的spark.conf而不是使用实际环境下的spark-defaults.conf。
解决方法：
首先，根据实际环境下的spark-defaults.conf找到以下用于规定日志输出的三个参数：
spark.eventLog.enabled
spark.yarn.historyServer.address
spark.eventLog.dir将上述三个参数拼接成用于spark-submit的conf信息：
--conf "spark.eventLog.enabled=true" --conf "spark.yarn.historyServer.address=node1.com:18081" --conf "spark.eventLog.dir=hdfs:///spark2-history/" 修改HiBench的"bin/functions/workload_functions.sh"文件，将上述conf信息添加至提交命令中，大概在216行（修改前请备份）：
修改前：
if [[ "$CLS" == *.py ]]; then
LIB_JARS="$LIB_JARS --jars ${SPARKBENCH_JAR}"
SUBMIT_CMD="${SPARK_HOME}/bin/spark-submit ${LIB_JARS} --properties-file ${SPARK_PROP_CONF} --master ${SPARK_MASTER} ${YARN_OPTS} ${CLS} $@"
else
SUBMIT_CMD="${SPARK_HOME}/bin/spark-submit ${LIB_JARS} --properties-file ${SPARK_PROP_CONF} --class ${CLS} --master ${SPARK_MASTER} ${YARN_OPTS} ${SPARKBENCH_JAR} $@"
fi修改后：
if [[ "$CLS" == *.py ]]; then
LIB_JARS="$LIB_JARS --jars ${SPARKBENCH_JAR}"
SUBMIT_CMD="${SPARK_HOME}/bin/spark-submit ${LIB_JARS} --conf "spark.eventLog.enabled=true" --conf "spark.yarn.historyServer.address=node1.com:18081" --conf "spark.eventLog.dir=hdfs:///spark2-history/" --properties-file ${SPARK_PROP_CONF} --master ${SPARK_MASTER} ${YARN_OPTS} ${CLS} $@"
else

问题原因：
作者本人的hadoop集群的HDFS是采用高可用部署的，namenode为active/standby模式，拥有一个namespace叫"mycluster"，因此默认在HiBench的conf/hadoop.conf中的配置信息为：
# The root HDFS path to store HiBench data
hibench.hdfs.master hdfs://mycluster
具体原因应该出自数据传输的实现，请见"com.intel.hibench.datagen.streaming.DataGenerator"。目测是该实现不支持namespace的访问方式，本人没有细究，有兴趣的可以去看下上述类的源码。
解决方法：
将上述conf/hadoop.conf中的配置信息修改为指定的namenode信息即可，例如：
# The root HDFS path to store HiBench data
hibench.hdfs.master hdfs://node1.com:8020===================================================================
其它：
SequenceFile格式化：
很多默认的HiBench的测试结果文件都是以SequenceFile进行输出的（mahout必须是SequenceFile），具体请见各个作业的执行脚本，例如Wordcount的run.sh（截取部分）：
run_hadoop_job ${HADOOP_EXAMPLES_JAR} wordcount \
-D mapreduce.job.maps=${NUM_MAPS} \
-D mapreduce.job.reduces=${NUM_REDS} \
-D mapreduce.inputformat.class=org.apache.hadoop.mapreduce.lib.input.SequenceFileInputFormat \
-D mapreduce.outputformat.class=org.apache.hadoop.mapreduce.lib.output.SequenceFileOutputFormat \
-D mapreduce.job.inputformat.class=org.apache.hadoop.mapreduce.lib.input.SequenceFileInputFormat \
-D mapreduce.job.outputformat.class=org.apache.hadoop.mapreduce.lib.output.SequenceFileOutputFormat \
${INPUT_HDFS} ${OUTPUT_HDFS}

为了方便阅读或是结果数据的后续使用，可通过如下方式进行转化：
使用FS SHELL进行文本输出：
sudo -u hdfs hadoop fs -text /path/xxx使用MR（转载）实现文件转换：

使用Spark（pyspark）：
# SparkSession available as 'spark'
reader=sc.sequenceFile("xxxx",keyClass="org.apache.hadoop.io.Text",valueClass="org.apache.hadoop.io.IntWritable")
# 直接打印出来
def out(x):
print x
reader.foreach(out)
# 转为sql
df=spark.read.json(reader.map(lambda x: x))
