tez will report an error

[study-day]

Data can only be read through hive. If you use hive to write input, tez will report an error.

Caused by: java.lang.RuntimeException: Failed to load plan: hdfs://hadoop-node-1:8020/tmp/hive/hdfs/010e1336-6251-4157-9499-e15efce79293/hive_2021-07-07_16-38-01_759_6301054491957594370-1/40e54cbd-439d-4e35-979a-fdc38dfa680f/map.xml: org.apache.hive.com.esotericsoftware.kryo.KryoException: Unable to find class: org.apache.carbondata.hive.MapredCarbonInputFormat

Hi, can you please provide the detailed query which you are trying to execute:
Like either you are facing the issue at the time of creating table or insert query.

Although from your error message it seems some problem with replacing the carbon jars. But before coming to conclusion we first need to check the query.
Please go through the documentation link
https://github.com/apache/carbondata/blob/master/docs/hive-guide.md

Here you will find the details about replacing the jars and write support with hive.
Please note that Only non-transactional tables are supported when created through hive.

I guess it has something to do with tez. But I don't know how to solve it, I switched to spark sql.

If you are not sure about the issue then can you please close it.
