## Description
When restarting IoTDB in MacOS, NullPointerException occurs and storage group failed to recover. 
!image-2021-11-30-09-00-54-672.png! 
## Cause
In MacOS, each directory contains a `.DS_store` file. When recovering compaction, IoTDB will search compaction log in each data directory, and it will treat .DS_store as a folder by mistake, which leads to NullPointException.
