Close the keystore file in SslContextAwareAbstractSource (#506)

Close the keystore file in SslContextAwareAbstractSource

The keystore was loaded through a FileInputStream that was never closed, both when validating the configuration and each time an SSLContext was created. The leaked handle keeps the keystore locked on Windows until the stream is garbage collected, which makes tests that place the keystore in a JUnit @TempDir fail during cleanup.

Welcome to Apache Flume!

Apache Flume is a distributed, reliable, and available service for efficiently collecting, aggregating, and moving large amounts of log data. It has a simple and flexible architecture based on streaming data flows. It is robust and fault tolerant with tunable reliability mechanisms and many failover and recovery mechanisms. The system is centrally managed and allows for intelligent dynamic management. It uses a simple extensible data model that allows for online analytic application.

The Apache Flume 1.x (NG) code line is a refactoring of the first generation Flume to solve certain known issues and limitations of the original design.

Apache Flume is open-sourced under the Apache Software Foundation License v2.0.

Compiling Flume

Compiling Flume requires the following tools:

Oracle Java JDK 1.8
Apache Maven 3.x

Note: The Apache Flume build requires more memory than the default configuration. We recommend you set the following Maven options:

export MAVEN_OPTS="-Xms512m -Xmx1024m"

To compile Flume and build a distribution tarball, run mvn install from the top level directory. The artifacts will be placed under flume-ng-dist/target/.
