Example
Submit a new U-SQL job to Data Lake Analytics.
// authenticate with service principal credentials
ApplicationTokenCredentials creds = new ApplicationTokenCredentials(_clientId, _tenantId, _clientSecret, null);
DataLakeAnalyticsJobManagementClient adlaJobClient = new DataLakeAnalyticsJobManagementClientImpl(creds);
// set up job parameters
UUID jobId = java.util.UUID.randomUUID();
USqlJobProperties properties = new USqlJobProperties();
properties.setScript("@input = EXTRACT Data string FROM \"/input1.csv\" USING Extractors.Csv(); OUTPUT @input TO @\"/output1.csv\" USING Outputters.Csv();");
JobInformation parameters = new JobInformation();
parameters.setName("testJob");
parameters.setJobId(jobId);
parameters.setType(JobType.USQL);
parameters.setProperties(properties);
// create the job
JobInformation jobInfo = adlaJobClient.getJobOperations().create(accountName, jobId, parameters).getBody();
