云- /*：糟糕的替代

Question

我试图在Cloud4.2Basic集群上运行BigInsights上的火花线作业，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

更深入地研究错误，我看到：

Error: Could not find or load main class org.apache.spark.executor.CoarseGrainedExecutorBackend

解决方案就在这里：http://www-01.ibm.com/support/docview.wss?uid=swg21987053

但是，我只需设置正确的iop.version：

--conf "spark.driver.extraJavaOptions=-Diop.version=4.2.0.0"
