Description

The POM dependency on okhttp in hadoop-hdfs-client declares its version in that POM instead.

the root declaration, including version, must go into the hadoop-project/pom.xml so that its easy to track use and have only one place if this version were ever to be incremented. As it stands, if any other module picked up the library, they could adopt a different version.
