BigQueryJobs.java

Job job = bigQueryClient.jobs().get(<プロジェクトID>, jobRef.getJobId()).execute();
if (job.getStatus().getErrorResult() != null) {
    log.warn(String.format("Job failed. job id:[%s] reason:[%s] status:[FAILED]", jobRef.getJobId(), job.getStatus().getErrorResult().getMessage()));
}
String jobStatus = job.getStatus().getState();
if (jobStatus.equals("DONE")) {
    JobStatistics statistics = job.getStatistics();
    log.info(String.format("Job statistics [%s]", statistics.getLoad()));
}
