Alexander Albul created SPARK-2346: -------------------------------------- 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: {quote} Exception in thread "main" java.lang.RuntimeException: [1.15] failure: ``('' expected but "123_table" found SELECT * FROM '123_table' ^ at scala.sys.package$.error(package.scala:27) at org.apache.spark.sql.catalyst.SqlParser.apply(SqlParser.scala:47) at org.apache.spark.sql.SQLContext.parseSql(SQLContext.scala:70) at org.apache.spark.sql.SQLContext.sql(SQLContext.scala:150) at io.ubix.spark.Test$.main(Test.scala:24) at io.ubix.spark.Test.main(Test.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:134) {quote} When i am changing from 123_table to table_123 problem disappears. -- This message was sent by Atlassian JIRA (v6.2#6252)
