報錯代碼

 def save(allTags: DataFrame): Unit = {
    //把最終結果保存到HBase
   allTags.write.format("cn.itcast.czxy.BD18.tools.HBaseDataSource")
        .option(HBaseMeta.ZKHOSTS, "192.168.10.20")
        .option(HBaseMeta.ZKPORT, "2181")
        .option(HBaseMeta.HBASETABLE, "test")
        .option(HBaseMeta.FAMILY, "detail")
        .option(HBaseMeta.SELECTFIELDS, "userId,tagsId")
        .save()
 }

修改後

def save(allTags: DataFrame): Unit = {
    //todo 關鍵代碼 : 重新劃分分區數量,解決內存溢出的問題
    val all: Dataset[Row] = allTags.repartition(10)
    //把最終結果保存到HBase
   all.write.format("cn.itcast.czxy.BD18.tools.HBaseDataSource")
        .option(HBaseMeta.ZKHOSTS, "192.168.10.20")
        .option(HBaseMeta.ZKPORT, "2181")
        .option(HBaseMeta.HBASETABLE, "test")
        .option(HBaseMeta.FAMILY, "detail")
        .option(HBaseMeta.SELECTFIELDS, "userId,tagsId")
        .save()
