Cannot Insert Data from Text File Format Table to Parquet Format Table, MapRedTask Error

itdm_bmi — Tue, 21 Apr 2026 06:50:18 GMT

Hi,

After Multi Delimiter Issue is solved. I got an error with data insertion.

So, after the data successfully inserted to text file format table with rowserde hive.contrib.serde2.MultiDelimitSerDe. Then i need to insert those data to parquet format table.

But when i ran the query to insert data, it failed.

Error message: "[FATAL] 10:25:08 vaproject.xxx tHiveRow_1 Error while processing statement: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask".

I used this script:

"INSERT OVERWRITE TABLE ParquetTable PARTITION (datadt=dateint) SELECT * FROM TextFileTable"

What is wrong or what am i missing? Please need your help. Thank you.

Sincerely,

Gideon Maruli

@itdm_bmi This error message is very generic. We could not say what caused the job to fail. Is it possible for you to share the YARN application log of application_1690451589703_12741 ?

You may collect it using the command :

yarn logs -applicationId application_1690451589703_12741 > /tmp/application_1690451589703_12741.log

Attach this application_1690451589703_12741.log file. If you are not comfortable sharing the log files here, you may file a support case. We'll be happy to assist.

Sorry took a long time to reply,

I couldn't find that application_id anymore. So i try new task, just simply data insertion query with application_id = application_1690451589703_37927

In log file i think i found the error. It is written

@itdm_bmi We are still seeing the error "java.lang.ClassNotFoundException: Class org.apache.hadoop.hive.contrib.serde2.MultiDelimitSerDe"

This means, you have not uploaded the "hive-contrib" jar to Hive classpath as mentioned here.

If you are on CDP(>7.1.5 onward) then, we will not have to upload hive-contrib jar to the class path. This serde class is already added to Hive native serde list.

You just need to alter the original table, and change the serde(Note: only applies to CDP version > 7.1.5)

ALTER TABLE <table name> SET SERDE 'org.apache.hadoop.hive.serde2.MultiDelimitSerDe'

If you are on an older version, do consider uploading to hive-contrib jar to hive classpath by uploading this to aux jar path location.
