今天使用阿里云druid.io服务,发现kafka-index-service这个任务都以失败结束,查询错误日志,错误如下

io.druid.java.util.common.ISE: Could not allocate segment for row with timestamp[2019-11-21T09:17:29.000Z]

傻缺,你看看你的
segmentGranularity和queryGranularity是不是写错了啊,一定要保证queryGranularity>=segmentGranularity

  "granularitySpec": {
      "type": "uniform",
      "segmentGranularity": "DAY",
      "queryGranularity": "DAY",
      "rollup": true
    }
