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

             Summary: SqlParser.parseTableIdentifier cannot recognize table name start with scientific notation
                 Key: SPARK-13934
                 URL: https://issues.apache.org/jira/browse/SPARK-13934
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.6.1
            Reporter: Yang Wang


SqlParser.parseTableIdentifier cannot recognize table name start with scientific notation like "1e30abcdedfg".
This bug can be reproduced by code following:
    val conf = new SparkConf().setAppName(s"test").setMaster("local[2]")
    val sc = new SparkContext(conf)
    val hc = new HiveContext(sc)
    val tableName = "1e34abcd"
    hc.sql("select 123").registerTempTable(tableName)
    hc.dropTempTable(tableName)

The last line will throw a RuntimeException.(java.lang.RuntimeException: [1.1] failure: identifier expected)
