Reynold Xin updated SPARK-7961: ------------------------------- Priority: Critical (was: Blocker) > Redesign SQLConf for better error message reporting > --------------------------------------------------- > > Key: SPARK-7961 > URL: https://issues.apache.org/jira/browse/SPARK-7961 > Project: Spark > Issue Type: Improvement > Components: SQL > Reporter: Reynold Xin > Priority: Critical > > Right now, we don't validate config values and as a result will throw > exceptions when queries or DataFrame operations are run. > Imagine if one user sets config variable "spark.sql.retainGroupColumns" > (requires "true", "false") to "hello". The set action itself will complete > fine. When another user runs a query, it will throw the following exception: > {code} > java.lang.IllegalArgumentException: For input string: "hello" > at > scala.collection.immutable.StringLike$class.parseBoolean(StringLike.scala:238) > at > scala.collection.immutable.StringLike$class.toBoolean(StringLike.scala:226) > at scala.collection.immutable.StringOps.toBoolean(StringOps.scala:31) > at > org.apache.spark.sql.SQLConf.dataFrameRetainGroupColumns(SQLConf.scala:265) > at org.apache.spark.sql.GroupedData.toDF(GroupedData.scala:74) > at org.apache.spark.sql.GroupedData.agg(GroupedData.scala:227) > {code} > This is highly confusing. We should redesign SQLConf to validate data input > at set time (during setConf call). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
