[FLINK-6836] [tests] Fix YARNSessionCapacitySchedulerITCase to work with
Hadoop 2.6.5, 2.7.3 and 2.8.0
Due to MNG-5899, maven cannot resolve dependency reduced poms in a multi
project build. Therefore, flink-yarn-tests pulls in a wrong version of
org.apache.httpcomponents.httpclient which does not work with Hadoop's
ServletUtils together. As a solution we have to move the dependency management
for the httpclient and httpcore version into the parent pom.xml.
Another problem is the version of these libraries which has been recently
bumped. In 4.4, httpclient changed its behaviour such that
URLEncodedUtils#parse(String, Charset) now throws a NPE if the first parameter
is null. In 4.2.6, an empty list was returned instead. Due to this
incompatibility, we reverted the change and set the version to its previous
value.
