Can I process multiline JSON data in HIVE ??

[debuggerrr]

I am able to create table and process data for single line JSON data but my question is can I process JSON data like below:

[{
    "field1": "data1",
    "field2": 100,
    "field3": "more data1",
    "field4": 123.001
}, {
    "field1": "data2",
    "field2": 200,
    "field3": "more data2",
    "field4": 123.002
}, {
    "field1": "data3",
    "field2": 300,
    "field3": "more data3",
    "field4": 123.003
}, {
    "field1": "data4",
    "field2": 400,
    "field3": "more data4",
    "field4": 123.004
}]

I have read that multiline JSON data wasn't supported in HIVE but can I use it now?? If yes, then please share the links where I can find this because I searched alot for this but I couldn't find any relevant material for this. Thanks in advance .

Do you have an actual file sample ? SerDe won't work unless there's one JSON record per line. R.

I want to load below JSON data and for that I am trying to create table as below:

CREATE TABLE my_table (field1 string, field2 int, field3 string, field4 double) ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe' ;

I added below JAR files :

• hive-json-serde.jar
• hive-json-serde-0.2.jar
• json-serde-1.3.6-SNAPSHOT-jar-with-dependencies.jar
• json-serde-1.3.jar
  but it gives me below error:
  FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Could not initialize class org.openx.data.jsonserde.objectinspector.JsonObjectInspectorFactory

  }, {
  "field1": "data4",
  "field2": 400,
  "field3": "more data4",
  "field4": 123.004
  }]

I referred many links from stackoverflow as well as from github but of no use. Please help me with this. Let me know where I am going wrong.

Since a nomal json should start wih '{' and end with '}', maybe you can remove the '[' and ']' and then set row format delimited fields terminated by ','
