> [FGL] Replace the global lock with global FS Lock and global BM lock
> --------------------------------------------------------------------
>
> Key: HDFS-17384
> URL: https://issues.apache.org/jira/browse/HDFS-17384
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: ZanderXu
> Assignee: ZanderXu
> Priority: Major
> Labels: FGL, pull-request-available
>
> First, we can replace the current global lock with two locks, global FS lock
> and global BM lock.
> The global FS lock is used to make directory tree-related operations
> thread-safe.
> The global BM lock is used to make block-related operations and DN-related
> operations thread-safe.
>
> For some operations involving both directory tree and block or DN, the global
> FS lock and the global BM lock are acquired.
>
> The lock order should be:
> * The global FS lock
> * The global BM lock
>
> There are some special requirements for this ticket.
> * End-user can choose to use global lock or fine-grained lock through
> configuration.
> * Try not to modify the current implementation logic as much as possible.
