Start by reproducing the HdfsReader-to-MySQL job with the JSON configuration and Java stack trace shown in the issue, then inspect the fastjson2 serialization path involved during HdfsReader initialization. Done means the job initializes without the reported StackOverflowError; the issue does not name repository files or tests to run.
