[SPARK-12941][SQL][MASTER] Spark-SQL JDBC Oracle dialect fails to map
string datatypes to Oracle VARCHAR datatype
## What changes were proposed in this pull request?
This Pull request is used for the fix SPARK-12941, creating a data type
mapping to Oracle for the corresponding data type"Stringtype" from dataframe.
This PR is for the master branch fix, where as another PR is already tested
with the branch 1.4
## How was the this patch tested?
(Please explain how this patch was tested. E.g. unit tests, integration
tests, manual tests)
This patch was tested using the Oracle docker .Created a new integration
suite for the same.The oracle.jdbc jar was to be downloaded from the maven
repository.Since there was no jdbc jar available in the maven repository, the
jar was downloaded from oracle site manually and installed in the local; thus
tested. So, for SparkQA test case run, the ojdbc jar might be manually placed
in the local maven repository(com/oracle/ojdbc6/11.2.0.2.0) while Spark QA test
run.
