[SPARK-14279][BUILD] Pick the spark version from pom

[dhruve]

Changes are already merged in master (#13061) . This one's for branch-2.0

@vanzin

With the current state being in the preview mode, users testing the framework would see the version as 2.0.0-SNAPSHOT as being mentioned in the pom file.

If this is acceptable, rest of the changes are as is.

[rxin]

hm maybe no need to do this for branch-2.0, since it's pretty easy to do this manually once or twice for 2.0.x.

[vanzin]

Dhruve points out above an instance where a previous release wasn't properly changed and now Spark is printing the wrong version in branch-2.0; so I think this change does help.

[vanzin]

ok to test

Personally I would like to see this go into branch-2.0 also. it doesn't seem very risky but has benefits to both dev and end users. @rxin do you have strong objections?

[rxin]

sounds good go ahead

[vanzin]

Merging to 2.0.

@dhruve could you close the PR? The bot doesn't do it automatically for backports. thx

[dhruve]

@vanzin. Thanks for reviewing & merging the PR. Have closed it.

spark-version-info.properties cannot be found in my develop machine, and will cause NPE while debugging with IDE, should we add the default version info back for developers like me?

[tgravescs]

@chenghao-intel can you file a jira with the details on what you are doing and link to the original jira?
