HADOOP-16986. S3A to not need wildfly on the classpath. (#1948)
HADOOP-16986. S3A to not need wildfly JAR on its classpath. Contributed by Steve Loughran This is a successor to HADOOP-16346, which enabled the S3A connector to load the native openssl SSL libraries for better HTTPS performance. That patch required wildfly.jar to be on the classpath. This update: * Makes wildfly.jar optional except in the special case that "fs.s3a.ssl.channel.mode" is set to "openssl" * Retains the declaration of wildfly.jar as a compile-time dependency in the hadoop-aws POM. This means that unless explicitly excluded, applications importing that published maven artifact will, transitively, add the specified wildfly JAR into their classpath for compilation/testing/ distribution. This is done for packaging and to offer that optional speedup. It is not mandatory: applications importing the hadoop-aws POM can exclude it if they choose.

### WildFly classpath requirements
|
||||
|
||||
For OpenSSL acceleration to work, a compatible version of the
|
||||
wildfly JAR must be on the classpath. This is not explicitly declared
|
||||
in the dependencies of the published `hadoop-aws` module, as it is
|
||||
optional.
|
||||
|
||||
If the wildfly JAR is not found, the network acceleration will fall back
|
||||
to the JVM, always.
|
||||
|
||||
Note: there have been compatibility problems with wildfly JARs and openSSL
|
||||
releases in the past: version 1.0.4.Final is not compatible with openssl 1.1.1.
|
||||
An extra complication was older versions of the `azure-data-lake-store-sdk`
|
||||
JAR used in `hadoop-azure-datalake` contained an unshaded copy of the 1.0.4.Final
|
||||
classes, causing binding problems even when a later version was explicitly
|
||||
being placed on the classpath.

||||
|
||||
