编译时没问题，提交运行错误，说明在运行环境中找不到StringUtils。
解决办法：
从/opt/sxt/hadoop-2.7.7/share/hadoop/tools/lib目录下拷贝commons-lang3-3.3..jar到opt/sxt/hadoop-2.7.7/share/hadoop/common/lib目录下，然后将commons-lang3-3.3..jar分别拷贝到各DataNode[root@node01 lib]# scp commons-lang3-3.3..jar node02:`pwd`
commons-lang3-3.3..jar % 403KB .1MB/s :
[root@node01 lib]# scp commons-lang3-3.3..jar node03:`pwd`

[root@node01 lib]# scp commons-lang3-3.3..jar node04:`pwd`
