Description

In SQOOP-2055 I've provided facility to not run multiple map task attempts by default in export case as that doesn't make sense in most scenarios. However looking closely into the patch, it seems that I did a small typo:

    int sqoopMaxAttempts = conf.getInt(SQOOP_EXPORT_MAP_TASK_MAX_ATTEMTPS, 1);
    if (sqoopMaxAttempts > 1) {
      conf.setInt(HADOOP_MAP_TASK_MAX_ATTEMTPS, sqoopMaxAttempts);
    }

Since SQOOP_EXPORT_MAP_TASK_MAX_ATTEMTPS is 1 by default, the if statement won't be called at all and hence we won't limit the number of attempts to 1 as expected. We should fix the condition to sqoopMaxAttempts >0 instead.
