[Project 1; Task 2] Output total number of pairs
This is a really dumb requirement.... Going to have the make a chained reducer to count the number of records
[Project 2] I didn't realize how terms were supposed to be used
starts up ─┐ times out,
│ ┌─────────starts ─────────┐ receives votes
│ │ election │ ┌────from majority ───┐
│ │ ▼ │ of servers ▼
│ ┌──────────┴─┐ ┌──────────┴─┐ ┌────────────┐
└────▶│ Follower │ ┌────│ Candidate │──┐ │ Leader │
└────────────┘ │ └────────────┘ │ └────────────┘
▲ ▲ discovers current ▲ │ │
│ │ leader or new term │times out, │
│ └─────────────┘ └───new ─┘ │
│ election │
│ │
│ │
│ │
└─────────────────────discovers server ─────────────────┘
with higher term
[Project 2] Fix leader election logic
[Project 2] Finish log replication implementation
Lack of copy trait on strings preventing Atomic operation
One remaining issue:
error[E0277]: the trait bound `std::string::String: std::marker::Copy` is not satisfied
--> src/server.rs:45:6

45 | impl Service for Server {
| ^^^^^^^ the trait `std::marker::Copy` is not implemented for `std::string::String`
|
= note: required because of the requirements on the impl of `std::marker::Sync` for `atomic::Atomic<std::string::String>`
= note: required because of the requirements on the impl of `std::marker::Send` for `std::sync::Arc<atomic::Atomic<std::string::String>>`
= note: required because it appears within the type `server::Server`
= note: required by `server::Service`

error: Could not compile `machine-project-2`.[Project 1; Task 1] Output total and unique word counts
Need to add a second chained MapReduce job to count the number of total and unique words. Will likely use a modification of the total pair count method from task 2 to add this functionality.
[Project 1; Task 2] Sort the elements of the pairs
