我事先已经将所需要的jar支持包全部拷贝到了各节点下的spark路径下的jar目录，但是在启动bin/spark-shell时总是报以上错误。在网上也看来很多解决方法，比如将缺失的jar包：hbase/lib 下 hbase*.jar,metrics*.jar.htrace*.jar 等拷贝到spark/jar目录，但这不正是我的启动准备工作吗，等于没说！

从故障根源分析，造成此错误的原因在于Spark启动的时候无法正常从我们的jar目录加载到它所需要的jar包（此处表现为/htrace-core-3.0.4.jar包）。所以，直接将包添加到jar目录是无法解决此问题的，而我们需要做的是给它指明CLASSPATH路径，在它不能找到所需要的jar包时就可以从此路径寻找。

解决办法：

在spark/conf目录下的spark-env.sh配置文件添加以下配置内容

export HBASE_CLASSPATH='hbase classpath'
export HADOOP_CLASSPATH='hadoop classpath'
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HBASE_CLASSPATH
