Errors trying to submit MessageHubIngest with streamx-runner

[pdettori]

I have been using latest version of streamsx-runner to submit. The command is:

streamsx-runner    --job-name    messagehub-ingest    --service-name    streaming-analytics    --main-composite    com.ibm.streamsx.clickstream.ingest::MessageHubIngest    --toolkits    $PRJ_HOME/streamsx.clickstream/sample/001_Clickstream_MessageHub_Ingest $PRJ_HOME/streamsx.clickstream/sample/000_Clickstream_DSX_Types $PRJ_HOME/streamsx.clickstream/com.ibm.streamsx.spl.util    --submission-parameters  "messageHubTopic=dsxClkStrm throttleRate=100000000.0 exportKind=dsxClkStrmTupleStream"

I ran in the following issues:

1. There was an error saying that the main composite com.ibm.streamsx.clickstream.ingest::MessageHubIngest was not visible. To fix that, I had to make it public.
2. Once the job starts, there is a problem with FileSinkClkStrm. It requires a data_directory configured, which cannot be provided with streamsx-runner (and it is not clear if that can be used with the bluemix service). So to make it work I had to comment that operator out.
