[SPARK-17619][SQL] To add support for pattern matching in ArrayContains
expression
## What changes were proposed in this pull request?
This change adds support for pattern matching in arrayContains expression
for the string arrays.
For eg.
a. arrayContains ( Seq ( â\\d\\d\\s-\\s\\d\\dâ, null, "",
"pattern"), "12 - 20" ) returns true
b. arrayContains ( Seq ( "\\d\\d\\s-\\s\\d\\d", "", "pattern"),
"132 - 20" ) ) returns false
c. arrayContains ( Seq ( "\\d\\d\\s-\\s\\d\\d", null, ââ,
"pattern"), "132 - 20" ) ) returns null
This change is completely backward compatible.
## How was this patch tested?
Added some more test cases for pattern match use case in the following:
a. CollectionFunctionsSuite.scala
b. DataFrameFunctionsSuite.scala
c. ExpressionToSQLSuite.scala
jira entry for detail: https://issues.apache.org/jira/browse/SPARK-17619
