Xiaogang Shi commented on FLINK-6557:
-------------------------------------

[~Zentol] Thanks a lot for pointing it out. As far as i know, the maximum length of directory paths in Windows is 260. The length of the path printed on the log however is only 181. Could you provide more information (e.g., stacks on exception) to help address the problem?

> The {{RocksDbStateBackendTest}} fails on windows when incremental checkpoint is enabled.
> Based on the exception i guess the file name is just simply too long:
