Setup

I’m getting an error that spark failed to ignite.

This may indicate that some other process is already using Spark and hasn’t been terminated. Restarting your computer should fix this.

I have a divergent branches error after trying the command git pull.

Run git config pull.rebase false and pull again.

I’m getting ‘Cannot invoke “ngordnet.ngrams.TimeSeries.years()” because “ILILILILIILILIILILIILIL” is null’

Re-pull the libraries in library-sp24.

I tried running git pull from library-sp24 but am still getting the above exception.

Be sure you’ve re-imported the libraries in IntelliJ after getting the new library files.

No matter what I do, the libraries still aren’t working!

Try deleting the library-sp24 entirely and re-cloning it.

I’m getting Failed to bind to /0.0.0.0:4567 when running Main.java.

Save your code and restart IntelliJ. If this doesn’t work, try restarting your computer as well.

How do I tiebreak words with the same counts?

It doesn’t matter for this project - any behavior is acceptable. This means you can break ties alphabetically, or randomly, or not at all!

How should I store total popularity of words?

Think about what you have implemented in Proj 2A. TimeSeries values are doubles, not ints. If you store the integer counts, you might get integer overflow.
