我有嵌套JSON的以下输入，我想将这些数据摄取到多行的hive中
"taxes": [{
"line_id": 1,
"commodity_code": "997159",
"fee": {
"amt": {
"curr_code": "USD",
"value": "71.4"
},
"type": "receiver"
},
"ship_addr": {
"admin_area_1": "MAHARASHTRA",
"country_code": "IN"
},
"total_tax": {

我使用以下DDL

FROM json_2002 t
LATERAL VIEW POSEXPLODE (split(get_json_object(json,'$.taxes[*].line_id'),'","')) e as i,x
LATERAL VIEW POSEXPLODE (split(get_json_object(json,'$taxes.tax_details[*].exempt_option'),'","')) f as g,h
答案 0 :(得分：0)
我可以使用regex_replace
解决问题LATERAL VIEW POSEXPLODE（split（regexp_replace（get_json_object（json，＆＃39; $。taxess.tax_details [*] .exempt_option＆＃39;），＆＃39; \ [| \]＆＃39;，＆＃ 39;＆＃39;），＆＃39;，＆＃39;））f为g，h
解决了我的问题
