Cannot validate serde : org.openx.data.jsonserde.jsonserde

Question

I have written this query to create a table on hive. My data is initially in json format, so i have downloaded and build serde and added all jar required for it to run. But i am getting the following error:

FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask. Cannot validate serde: org.openx.data.jsonserde.JsonSerDe

QUERY:

create table tip(type string,
  text string,
  business_id string,
  user_id string,
  date date,
  likes int)
ROW FORMAT SERDE 'org.openx.data.jsonserde.JsonSerDe'
WITH SERDEPROPERTIES("date.mapping"="date")
STORED AS TEXTFILE;

could you find any solution for this error. I have the same problem and I don't know why. — xxlali

I too encountered this problem. In my case, I managed to fix this issue by adding json-serde-1.3.7-SNAPSHOT-jar-with-dependencies.jar at hive command prompt as shown below:

hive> ADD JAR /usr/local/Hive-JSON-Serde/json-serde/target/json-serde-1.3.7-SNAPSHOT-jar-with-dependencies.jar;

Below are the steps I have followed on Ubuntu 14.04:

1. Fire up Linux terminal and cd /usr/local

2. sudo git clone https://github.com/rcongiu/Hive-JSON-Serde.git

3. sudo mvn -Pcdh5 clean package

4. The serde file will be in 
   /usr/local/Hive-JSON-Serde/json-serde/target/json-serde-1.3.7-SNAPSHOT-jar-with-dependencies.jar

5. Go to hive prompt and ADD JAR file as shown in Step 6.

6. hive> ADD JAR /usr/local/Hive-JSON-Serde/json-serde/target/json-serde-1.3.7- SNAPSHOT-jar-with-dependencies.jar;

7. Now create hive table from hive> prompt. At this stage, Hive table should be created successfully without any error.

Hive Version: 1.2.1

Hadoop Version: 2.7.1
