Answer 1

You've got error messages that show clearly that you have an incomplete CLASSPATH.
That's because the pig command line does a lot of things, among which setting up silently the appropriate Pig JARs in the CLASSPATH, before invoking the PigMain Java class. But Oozie calls the Java class directly; the CLASSPATH issues are supposed to be handled either...
by the Pig ShareLib, when active
or by you, as a knowledgeable Java developer -- after all, it's your
choice not to use the default way to run Pig, so you know what you
are doing, right?
Before asking your question, did you try a search on StackOverflow (and/or Google) with the following keywords? The results could prove useful.
oozie pig custom classpath

Answer 2

In the above case have you checked if you are able to access Pig CLI {grunt shell} or are you able to running Pig Script manually, without Using Oozie.
The Case what happend is Pig Jar was not accessable while You are trying to use via Oozie, the Best Case to avoide such issue is to use Oozie - -ShareLib , but as You mention you dnt want the same to work using sharedlib, then use some alternate case like:
Update Pig Home Path in Hadoop ClassPath. These will help MR to fetch the List of Jars in HDFS Temp Location every time Oozie Submit Request to MR.
Update Pig Home in BashProfile {if Pig shows error while accessing GRANT Shell with Command not Found}.
Hope these will help some.
