测试Hadoop到Teradata流程(Testing Hadoop to Teradata flow [closed])
我想测试一个hadoop datalake和teradata表之间的流程。 问题是我对这些技术不熟悉。 数据湖是我用于teradata的数据仓库的数据源。 我读了一下QuerySurge,但我想知道是否可以创建自己的脚本来测试流程。
I would like to test a flow between an hadoop datalake and teradata tables. The thing is that I am new to these technologies. The data lake is my data source for the datawarehouse I have on teradata. I read about QuerySurge but I'd like to know if it is possible to create my own scripts to test the flows.

你可以使用
HashSet<ArrayList<String>>
,也许这会起作用? 或者您可以使用.contains()
方法检查List是否包含元素而不是containsAllYou could use a
HashSet<ArrayList<String>>
, maybe that would work? Or you could use the.contains()
method to check if the List contains the element instead of containsAll

它不会添加多个副本,它总是在第一次迭代之后将f添加为一个新的列表项,然后在您的列表中选择f,f,f,f,f,f,f,f,f。 而且你总是修改你的唯一数组f,所以所有的元素都表示相同的两个数字 你应该改变: for(int j=0; j<2; j++){ f[0] = i; 至 for(int j=0; j<2; j++){ f = new int [2]; f[0] = i; 我不明白你的情况 if(!(G.contains(f))){ f从来不在G中,因为你永远不会把它放在那里,所以没有可能到达那里 ...

这是行不通的,因为你一直在处理对单个列表的引用,所以它总是在第一次追加它后出现在列表中。 考虑: perms = [] items = [1, 2, 3] random.shuffle(mylist) # perhaps items is now [2, 1, 3] perms.append(items) # perms is now [[2, 1, 3]] random.shuffle(mylist) # perhaps items is now [1, 3, 2] perms.appe ... -
