You must file in both states. That's because both AZ and CA are both community property states. Here is AZ's rule on your situation:
If your nonresident spouse is a resident of a community property state, then the total community income will include income from both Arizona and the state where your spouse is a resident. Total community income would include wages you and your spouse (if a resident of a community property state) earn while you are married.

As an AZ resident, ALL your income is taxable by AZ. Since you have community income from your husband's job in CA, you must file an AZ tax return.
