大数据分析报错 An error occurred while returning the result

做大数据分析的时候，Portal报错，An error occurred while returning the result, however, the result should still be available in your Portal，但是我在监控Http请求时发现，其实分析是成功的了，分析结果的条数也可以读到。但是好像是写不进DataStore，然后就报错了

查看server的报错日志，其中有一条 Write failures may occur because the number of potential concurrent writers is much larger than the number of nodes in the data store. 不晓得跟这个有没有关系
