I am trying to run a sample impala query using ozzie. While running shell I am getting below error
Error: E0701 : E0701: XML schema error, cvc-complex-type.2.3: Element 'shell' cannot have character [children], because the type's content type is element-only.

I checked..this is a valid XML.first_impala.iql has a select count(*) query.
The Oozie validate command says that's valid XML. I recently encountered the same error message for my own XML though. It was caused by some invalid whitespace characters that somehow got into my XML (a stray copy/paste most likely). Try removing all the leading/trailing whitespace from each line, and look for any other characters that may not be valid. Stack Overflow might have stripped the invalid characters from your post.
