command exit value(247)

job执行日志中没有 ERROR 信息， 就是执行时间比较长，最后执行状态为失败

datax-web job execute end(finish) -----------
----------- ReturnT:ReturnT [code=500, msg=command exit value(247) is failed, content=null]

No file, test, or entry point is named; the report only provides a long-running job's log excerpt and exit value 247. Start by reproducing the failing job and tracing the datax-web command execution path and exit-status handling; done means identifying the failure cause and documenting or testing the corrected behavior.
