I have an installed CDH cluster and used hadoop version, but it returns only with Hadoop version. Is there any way to get maybe all installed components version number on a graphical interface? Which command can get for example Spark version number?
While individual components might have a version in some kind of UI, not all even have a UI. They don't have some consistent programmatic identifier. The next-best thing is to grep the names of JAR files in the distribution, if you really had to do it programmatically.
