```
Actually, it's not the leaderId. It has 8-4-4-4-12 pattern
It is defined as UUID.
```java
private UUID leaderId;
```
The ReplicaIndex on the other hand has 9-4-4-4-12
0b63db24b-9d73-45ea-84eb-78dca9f54b6d
```java
private final PipelineID id;
```
## What has been done?
Provide better message when calling Pipeline#toString
the new format is
```
