----------------------------------------
Summary: Sparksql-1.4.1 DataFrameWrite.jdbc() bug
Key: SPARK-11623
URL: https://issues.apache.org/jira/browse/SPARK-11623
Project: Spark
Issue Type: Bug
Components: Java API, Spark Submit, SQL
Affects Versions: 1.5.1, 1.4.1
Environment: Spark stand alone cluster
Reporter: Nguyen Van Nghia
I am running spark-submit in window 8.1 with spark standalone cluster (01
worker and 01 master), the job throw Exception in DataFrameWrite.jdbc(..)
scala function.
We found that the following test:
var tableExists = JdbcUtils.tableExists(conn, table)
always return false event if we already created a table. That drive the
function to do creating table from specified DataFrame and the SQL Syntax
error for creating table, we locate the SQL execution statement hereafter:
if (!tableExists) {
val schema = JDBCWriteDetails.schemaString(df, url)
val sql = s"CREATE TABLE $table ($schema)"
conn.prepareStatement(sql).executeUpdate() // This execution cause sql
syntax error
}
This happened with spark-1.4.1 and Spark-1.5.1 (our dev environment).
Please help!
