我正在尝试在云上的biginsights上运行火花纱工作4.2基本群集，但我遇到了以下问题：
Stack trace: ExitCodeException exitCode=1: /data/hadoop-swap/yarn/local/usercache/snowch/appcache/application_1480680664469_0038/container_1480680664469_0038_01_000004/launch_container.sh: line 24: $PWD:$PWD/__spark__.jar:/etc/hadoop/conf:/usr/iop/current/hadoop-client/*:/usr/iop/current/hadoop-client/lib/*:/usr/iop/current/hadoop-hdfs-client/*:/usr/iop/current/hadoop-hdfs-client/lib/*:/usr/iop/current/hadoop-yarn-client/*:/usr/iop/current/hadoop-yarn-client/lib/*:/usr/lib/hadoop-lzo/lib/*:/etc/hadoop/conf/:$PWD/mr-framework/hadoop/share/hadoop/mapreduce/*:$PWD/mr-framework/hadoop/share/hadoop/mapreduce/lib/*:$PWD/mr-framework/hadoop/share/hadoop/common/*:$PWD/mr-framework/hadoop/share/hadoop/common/lib/*:$PWD/mr-framework/hadoop/share/hadoop/yarn/*:$PWD/mr-framework/hadoop/share/hadoop/yarn/lib/*:$PWD/mr-framework/hadoop/share/hadoop/hdfs/*:$PWD/mr-framework/hadoop/share/hadoop/hdfs/lib/*:$PWD/mr-framework/hadoop/share/hadoop/tools/lib/*:/usr/iop/${iop.version}/hadoop/lib/hadoop-lzo-0.5.1.jar:/etc/hadoop/conf/secure:/usr/lib/hadoop-lzo/lib/*: bad substitution
更深入地挖掘错误，我看到：
Error: Could not find or load main class org.apache.spark.executor.CoarseGrainedExecutorBackend
解决方案在这里：http：//www-01.ibm.com/support/docview.wss?uid=swg21987053
但是，我只需要设置正确的iop.version：
--conf "spark.driver.extraJavaOptions=-Diop.version=4.2.0.0"
