Now we will try to write the entire algorithm in Spark. Spark does not have a default implementation of Apriori algorithm, so we will have to write our own implementation as shown next (refer to the comments in the code as well). First, we will have the regular boilerplate code to initiate the Spark configuration and context.

There Apriori algorithm has been implemented as Apriori.java(version 2).

A Java applet which combines DIC, Apriori and Probability Based Objected Interestingness Measures can be found here.

Note: Java 1.6.0_07 or newer

- The following java project contains the java source code and java examples used for des algorithm implementation (encryption). DES encrypts and decrypts data in 64-bit blocks, using a 64-bit key (although the effective key strength is only 56 bits, as explained below).

- Apriori.java: Simple implementation of the Apriori Itemset Generation algorithm.
- Version 2: Apriori Itemset Generation algorithm that uses a hash tree.

- config.txt: Consists of four lines.
- Number of items
- Number of transactions
- Minimum support i.e. 20 represents 20%
*minsup* - Size of step M for the DIC algorithm. This line is ignored by the Apriori algorithm

- transa.txt: Contains the transaction database as an
*m*x*n*matrix. Transaction 1 appears in row one. Columns are separated by a space and represent items. A 1 indicates that item is present in the transaction and a 0 indicates it is not. The transaction file for the following example (and many other datasets) can be found on the datasets page.

##### Place Apriori.java in a directory called apriori

##### Compile the .java file:

##### Change config.txt and transa.txt to represent the database and criteria to be tested.

##### Run the programs:

## Example

We use the database from Apriori Itemset Generation example #2. The *minsupp* is 40%.

Press 'C' to change the default configuration and transaction files

or any other key to continue.

Input configuration: 5 items, 5 transactions, minsup = 40%

Frequent 1-itemsets:

[1, 2, 3, 4, 5]

Frequent 2-itemsets:

[1 2, 1 3, 1 4, 1 5, 2 3, 2 4, 3 4, 3 5, 4 5]

We get the same results as we did earlier when we did the Apriori algorithm by hand.
