I am writing data to hdfs file, also the hdfs dir is a hive partition file dir. Hive does not support sub dirs.. for example my partition folder is ***/dt=20170224/hm=1400 that means I need to write all the data between 1400 to 1500 to the same folder.

In the past I partitioned by executor id. I don't know if this is the best way though.

When my spark.streaming.concurrentJobs is more than one. Like 20. I meet the exception as below. We know that when the batch finished, there will be a _SUCCESS file. As I guess my spark application, if one batch is slow, and the another one run at the same time, two spark streaming batch may be try to make use of the _SUCCESS file at the same time. So the error as below happened Anyone knows that whether I am right. Or any suggestions to avoid this problem?
