What changes were proposed in this pull request?
In the History Server DiskManager, when acquiring a lease, a temporary directory is created on the disk, and a JVM shutdown hook is registered used to remove this temporary directory. When the lease is committed or rolled back, the temporary directory is either renamed to the target directory or deleted, but the registered JVM shutdown hook remains in the ShutdownHookManager, causing a memory leak. Additionally, a large number of residual hooks will execute when the History Server restarts, severely slowing down the restart process.
Why are the changes needed?
We should remove residual hooks when lease committed or rolled back.
