this pr is used to fix the invalid format load for stream load.
before the change , we will get the error when we load the invalid array format.
the origin file to load :
1 [1, 2, 3]
2 [4, 5, 6]
3 \N
4 [7, \N, 8]
5 10, 11, 12

}
3. after this change, we will get success and the error url which report the error line.
