spark模型error java.lang.IllegalArgumentException: Row length is 0

Posted 2022-12-07 shaozhiqi

failure: Lost task 18.3 in stage 17.0 (TID 59784,XXXXX, executor 19): java.lang.IllegalArgumentException: Row length is 0

场景是写入hbase：

val put = new Put(Bytes.toBytes(line._1))

当取出的line._1做为row,值是“”或者null时就会出现此异常。所以做如下处理，先过滤掉为null和“”的数据

    val bhaseRdd = resultRdd.filter(r => 
      r._1 != "" && r._1!=null&&r._1.length>0
    ).map(line => 
      val put = new Put(Bytes.toBytes(line._1)) //rowKey 为参数，拿到put
      val key = line._2.keySet().iterator(); //拿到对应的dataMap
    ........
