问题描述
我试图使用运行命令行星火例如code HBaseTest火花，而不是提交运行的例子，在这种情况下，我可以学到更多如何运行一般的火花code。
I am trying to run the Spark example code HBaseTest from command line using spark-submit instead run-example, in that case, I can learn more how to run spark code in general.
不过，因为我使用CDH5.4告诉我关于htrace CLASS_NOT_FOUND。我成功地位于htrace jar文件，但我有一个很难将其添加到路径。
However, it told me CLASS_NOT_FOUND about htrace since I am using CDH5.4. I successfully located the htrace jar file but I am having a hard time adding it to path.
这是最后的火花提交命令我有，但仍然有类未找到错误。谁能帮助我？
This is the final spark-submit command I have but still have the class not found error. Can anyone help me with this?
#!/bin/bash
export SPARK_HOME=/opt/cloudera/parcels/CDH/lib/spark
/bin/bash $SPARK_HOME/bin/spark-submit \
--master yarn-client \
--class org.apache.spark.examples.HBaseTest \
--driver-class-path /etc/hbase/conf:$SPARK_HOME/examples/lib/*.jar:/opt/cloudera/parcels/CDH-5.4.2-1.cdh5.4.2.p0.2/lib/hbase/lib/*.jar \
--jars $SPARK_HOME/examples/lib/*.jar:/opt/cloudera/parcels/CDH-5.4.2-1.cdh5.4.2.p0.2/lib/hbase/lib/*.jar \
$SPARK_HOME/examples/lib/*.jar \
myhbasetablename
请注意：
htrace核心-3.0.4.jar，htrace核-3.1.0-incubating.jar，htrace-core.jar添加都设下/opt/cloudera/parcels/CDH-5.4.2-1.cdh5.4.2 .p0.2 / lib目录/ HBase的/ lib目录/'。
Note: htrace-core-3.0.4.jar, htrace-core-3.1.0-incubating.jar, htrace-core.jar are all located under '/opt/cloudera/parcels/CDH-5.4.2-1.cdh5.4.2.p0.2/lib/hbase/lib/'.
推荐答案
我打开了 $ SPARK_HOME / conf目录/ classpath.txt 和刚添加的 /opt/cloudera/parcels/CDH/lib/hbase/lib/htrace-core-3.1.0-incubating.jar 到文件的末尾。
I opened up the $SPARK_HOME/conf/classpath.txt and just added the /opt/cloudera/parcels/CDH/lib/hbase/lib/htrace-core-3.1.0-incubating.jar to the end of the file.
