It's a general > option, so let me add it as a first parameter: > > ./flink -v run ../examples/flink-java-examples-0.8.0-WordCount.jar > > hdfs:///input hdfs:///output9 > Invalid action! > ./flink <ACTION> [GENERAL_OPTIONS] [ARGUMENTS] > general options: > -h,--help Show the help for the CLI Frontend. > -v,--verbose Print more detailed error messages. > Action "run" compiles and runs a program. > Syntax: run [OPTIONS] <jar-file> <arguments> > "run" action arguments: > -c,--class <classname> Class with the program entry point > ("main" > method or "getPlan()" method. Only > needed > if the JAR file does not specify the > class > in its manifest. > -m,--jobmanager <host:port> Address of the JobManager (master) to > which to connect. Use this flag to > connect > to a different JobManager than the one > specified in the configuration. > -p,--parallelism <parallelism> The parallelism with which to run the > program. Optional flag to override the > default value specified in the > configuration. > Action "info" displays information about a program. > "info" action arguments: > -c,--class <classname> Class with the program entry point > ("main" > method or "getPlan()" method. Only > needed > if the JAR file does not specify the > class > in its manifest. > -e,--executionplan Show optimized execution plan of the > program (JSON) > -m,--jobmanager <host:port> Address of the JobManager (master) to > which to connect. Use this flag to > connect > to a different JobManager than the one > specified in the configuration. > -p,--parallelism <parallelism> The parallelism with which to run the > program. Optional flag to override the > default value specified in the > configuration. > Action "list" lists running and finished programs. > "list" action arguments: > -m,--jobmanager <host:port> Address of the JobManager (master) to which > to connect. Use this flag to connect to a > different JobManager than the one specified > in the configuration. > -r,--running Show running programs and their JobIDs > -s,--scheduled Show scheduled prorgrams and their JobIDs > Action "cancel" cancels a running program. > "cancel" action arguments: > -i,--jobid <jobID> JobID of program to cancel > -m,--jobmanager <host:port> Address of the JobManager (master) to which > to connect. Use this flag to connect to a > different JobManager than the one specified > in the configuration. > What just happened? This results in a lot of output which is usually > generated if you use the --help option on command-line tools. If your > terminal window is large enough, then you will see a tiny message: > "Please specify an action". I did specify an action. Strange. If you read the > help messages carefully you see, that "general options" belong to the action. > > ./flink run -v ../examples/flink-java-examples-0.8.0-WordCount.jar > > hdfs:///input hdfs:///output9 > For the sake of mitigating user frustration, let us also accept -v as the > first argument. It may seem trivial for the day-to-day Flink user but makes a > difference for a novice. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
