使用多个chanal的时候hive中数据重复

Contributor guide

No contributing guide indexed for this repository

Research direction

Start by reproducing the MongoDB-to-Hive transfer with multiple channels and compare the records written to Hive. Trace the relevant DataX reader and writer entry points to determine where duplicates appear; done means the same source records are written without duplication when multiple channels are enabled.
