OceanBasewriter中如果已经开始了InsertTask ,若出现异常则datax就不会停止了，一直死循环,希望官方修复一下

OceanBasewriter，在insert时如果出现错误（已经启动了Inserttask线程），则如果出现有异常就不会停止。

Start by reproducing the failure in OceanBasewriter during insert after an InsertTask thread has started, then inspect the InsertTask lifecycle and its exception handling. Done means the DataX job stops instead of looping indefinitely when the insert operation raises an exception.
