> This is going to make analysis/evolution of the code more complex, so I want to understand better why are we doing this ? What is the current issue/bottleneck and how much of it is mitigated by this change ? The goal is to fix the deadlock that is described in detail in [SPARK-36782](https://issues.apache.org/jira/browse/SPARK-36782). From our testing this deadlock is common enough meaning that we can not use the decommission features introduced in 3.1.1, since when the deadlock happens the driver does not seem to recover and the spark job en up failing. The patch should remove the possibility of this deadlock by making the `BlockManagerMasterEndpoint` not block when responding to calls with `UpdateBlockInfo`. -- This is an automated message from the Apache Git Service.
