--------------------------------------

             Summary: Error parsing table names that starts from numbers
                 Key: SPARK-2346
                 URL: https://issues.apache.org/jira/browse/SPARK-2346
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.0.0
            Reporter: Alexander Albul


Looks like org.apache.spark.sql.catalyst.SqlParser cannot parse table names 
when they start from numbers.

Steps to reproduce:

{code:title=Test.scala|borderStyle=solid}
case class Data(value: String)

object Test {
  def main(args: Array[String]) {
    val sc = new SparkContext("local", "sql")
    val sqlSc = new SQLContext(sc)
    import sqlSc._

    sc.parallelize(List(Data("one"), Data("two"))).registerAsTable("123_table")
    sql("SELECT * FROM '123_table'").collect().foreach(println)
  }
}
{code}

And here is an exception:

Exception in thread "main" java.lang.RuntimeException: [1.15] failure: ``('' 
expected but "123_table" found

SELECT * FROM '123_table'

When i am changing from 123_table to table_123 problem disappears.
