Alexander Albul updated SPARK-2346:
-----------------------------------
Description:
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:
{quote}
Exception in thread "main" java.lang.RuntimeException: [1.15] failure: ``(''
expected but "123_table" found
SELECT * FROM '123_table'
^
