在输入中,我有要在配置单元中导入的文件json:
from sshtunnel import SSHTunnelForwarder
import time
server = SSHTunnelForwarder(
'server_ip_address',
ssh_username="user",
ssh_password="password",
local_bind_address=('127.0.0.1', 8080),
remote_bind_address=('127.0.0.1', 3128),
)
server.start()
print(server.local_bind_port) # show assigned local port
# work with `SECRET SERVICE` through `server.local_bind_port`.
while True:
time.sleep(1)
server.stop()
我试图用以下复杂类型捕获此信息:

您没有提到任何有关遇到的错误的信息。通常,使用JSON SerDe时要注意两点。
org.apache.hadoop.hive.serde2.JsonSerDe 不支持以方括号'['
JsonSerDe基于文本SerDe,并且每个换行符都被视为新记录
有效格式:
{"world_rank": "1","country": "China","population": "1388232694","World": "0.185"},
{"world_rank": "2","country": "India","population": "1342512706","World": "0.179"},
{"world_rank": "3","country": "U.S.","population": "326474013","World": "0.043"},
{"world_rank": "4","country": "Indonesia","population": "263510146","World": "0.035"}
无效的格式1:

无效的格式2:

输入数据应先预处理为以下格式,然后再加载到Hive表中
