oozie server系統時鐘偏差導致sqoop報錯

使用oozie通過sqoop導數報錯如下

Failing Oozie Launcher, Main class [org.apache.oozie.action.hadoop.SqoopMain], main() threw exception, begin > end in range (begin, end): (1464673410428, 1464673380508)

通過查找源代碼發現如下問題

long startTime = 0L;
try {
    startTime = Long.parseLong((System.getProperty("oozie.job.launch.time")));
} catch(NumberFormatException nfe) {
throw new RuntimeException("Could not find Oozie job launch time", nfe);
}
String tag = actionConf.get("mapreduce.job.tags");
if (tag == null) {
throw new RuntimeException("Could not find Yarn tags property (mapreduce.job.tags)");
}
GetApplicationsRequest gar = GetApplicationsRequest.newInstance();
gar.setScope(ApplicationsRequestScope.OWN);
gar.setStartRange(startTime, System.currentTimeMillis());

public void setStartRange(long begin, long end) throws IllegalArgumentException {
if(begin > end) {
throw new IllegalArgumentException("begin > end in range (begin, end): (" + begin + ", " + end + ")");
    } else {
this.start = new LongRange(begin, end);
    }
}

分析得知是由於oozie job啓動時間大於系統當前時間，去查cloudera oozie server發現兩臺oozie server中一臺存在時鐘偏差，由於是測試環境，直接將oozie ha禁用，只保留沒有時鐘偏差的server，重跑job問題解決。

當然後續必須得解決時鐘偏差問題了，報錯以作記錄備忘。
