[BUG] title Worker not getting resources (Slots)

[yangbin09]

---

Description:

After starting the Celeborn Worker, the following issues occur:

1. Worker not getting resources (Slots)
   The logs show:

   maxSlots: 0
   activeSlots: 0
   

   This indicates that the Worker is not being allocated any resources, preventing it from executing any tasks.

2. Incorrect disk space information
   In the heartbeat message sent from the Worker to the Master, the disk space shows:

   usableSpace: 8.0 EiB
   totalSpace: 0.0 B
   

   This suggests that the Worker is not correctly detecting the disk space, which may indicate a problem with the storage path or mount.

3. No running Shuffle tasks
   The logs show:

   committed shuffles: 0
   running applications: 0
   

   This indicates that no tasks are being submitted to the Worker, likely due to insufficient resources or failed shuffle allocation.

4. Memory management is normal, but no Shuffle operations are taking place
   Even though memory usage is normal:

   Direct memory usage: 4.0 MiB/1024.0 MiB
   

   No shuffle operations are occurring due to the lack of available resources.

Steps to Reproduce:

1. Start the Celeborn Worker.
2. Start a Spark job that performs a shuffle operation.
3. Check the logs of the Celeborn Worker, paying attention to the maxSlots, activeSlots, usableSpace, totalSpace, and committed shuffles fields.
