I tested it and found that if the "field A" field in the dataframe is removed,
it can be written to mysql normally; if "field A" is written, the same error
will be reported.
The value of field A is approximately 1000 bytes in length.
If you change the running mode of the program in app-env.sh to local and client
mode, you can write to mysql normally; use yarn and cluster mode, and report
the error in the attached log.
Is this error related to the cluster version and configuration?
