Summary: Fix NullPointerException when recovering compaction in
MacOS
Key: IOTDB-2074
URL: https://issues.apache.org/jira/browse/IOTDB-2074
Project: Apache IoTDB
Issue Type: Bug
Reporter: Liuxuxin
Assignee: Liuxuxin
Fix For: 0.13.0
Attachments: image-2021-11-30-09-00-54-672.png
## 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.
