Tasks are not uniformly distributed across Dask workers #7093

Description

@JaguarPaw2409

Describe the issue:
Tasks are not uniformly distributed across all the available dask workers. The majority of the tasks, are getting piled up on a single worker. Is this an expected behavior?

Dask-Status

Workers

Anything else we need to know?:
The cluster is adaptive and the rest of the workers were added after 1-2 minutes. Why the pending tasks are not getting routed to the new workers?

Environment:

  • Dask version: 2.30.0
  • Distributed version: 2.30.1
  • Python version: 3.7.10
  • Operating System: CentOS Linux 7 (Core)
  • Install method (conda, pip, source): pip
