[GitHub] [iotdb] JackieTien97 opened a new pull request #2558: Fix delete dead lock

JackieTien97 opened a new pull request #2558:
URL: https://github.com/apache/iotdb/pull/2558


   In the process of querying, we first acquire the tsFileManagement lock and then acquire writeLock in sgProcessor. However, in the process of deleting, we acquire writeLock in sgProcessor firstly, and then acquire the tsFileManagement lock. This will cause deadlock in IoTDB.
