# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.

# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.

# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite

Securing Apache Spark with Apache Shiro

1. Download shiro-core-1.2.5.jar Apache Shiro Downloads
2. Download shiro-web-1.2.5.jar Apache Shiro Downloads
3. Note the location of the JAR files and shiro.ini. I placed it in the root of my Spark download
4. Update the spark-env.sh file with the Shiro JARs and add an entry for the path where the shiro.ini resides
5. Start the Spark master sbin/start-master.sh
6. Navigate to the Spark master dashboard
7. Authenticate with credentials in shiro.ini

Note this was developed / tested with Apache Spark 1.4.1, but should work with newer versions as well.
