Description

1. 1. Description
      When restarting IoTDB in MacOS, NullPointerException occurs and storage group failed to recover.
      
   2. Cause
      In MacOS, each directory contains a `.DS_store` file. The .DS_store under virtual storage group will cause problem. 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.
