Does this mean there is a possible mismatch of jdbc driver with oracle? From: Ted Yu [mailto:yuzhih...@gmail.com] Sent: Friday, July 17, 2015 2:09 PM To: Sambit Tripathy (RBEI/EDS1) Cc: user@spark.apache.org Subject: Re: What is "java.sql.SQLException: Unsupported type -101"?
Looking at getCatalystType(): * Maps a JDBC type to a Catalyst type. This function is called only when * the JdbcDialect class corresponding to your database driver returns null. sqlType was carrying value of -101 However, I couldn't find -101 in http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b14/java/sql/Types.java FYI On Fri, Jul 17, 2015 at 2:01 PM, Sambit Tripathy (RBEI/EDS1) <sambit.tripa...@in.bosch.com<mailto:sambit.tripa...@in.bosch.com>> wrote: Hi, I was trying to get a oracle table using JDBC datasource val jdbcDF = sqlContext.load("jdbc", Map( "url" -> "jdbc:oracle:thin:USER/p...@host.com:1517:sid", "dbtable" -> "USER.TABLE","driver" -> "oracle.jdbc.OracleDriver")) and got the error below java.sql.SQLException: Unsupported type -101 at org.apache.spark.sql.jdbc.JDBCRDD$.getCatalystType(JDBCRDD.scala:78) at org.apache.spark.sql.jdbc.JDBCRDD$.resolveTable(JDBCRDD.scala:112) at org.apache.spark.sql.jdbc.JDBCRelation.<init>(JDBCRelation.scala:133) at org.apache.spark.sql.jdbc.DefaultSource.createRelation(JDBCRelation.scala:121) at org.apache.spark.sql.sources.ResolvedDataSource$.apply(ddl.scala:219) at org.apache.spark.sql.SQLContext.load(SQLContext.scala:697) at $iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC.<init>(<console>:23) at $iwC$$iwC$$iwC$$iwC$$iwC$$iwC$$iwC.<init>(<console>:28) at $iwC$$iwC$$iwC$$iwC$$iwC$$iwC.<init>(<console>:30) at $iwC$$iwC$$iwC$$iwC$$iwC.<init>(<console>:32) at $iwC$$iwC$$iwC$$iwC.<init>(<console>:34) at $iwC$$iwC$$iwC.<init>(<console>:36) at $iwC$$iwC.<init>(<console>:38) at $iwC.<init>(<console>:40) at <init>(<console>:42) at .<init>(<console>:46) at .<clinit>(<console>) at .<init>(<console>:7) at .<clinit>(<console>) at $print(<console>) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.apache.spark.repl.SparkIMain$ReadEvalPrint.call(SparkIMain.scala:1065) at org.apache.spark.repl.SparkIMain$Request.loadAndRun(SparkIMain.scala:1338) at org.apache.spark.repl.SparkIMain.loadAndRunReq$1(SparkIMain.scala:840) at org.apache.spark.repl.SparkIMain.interpret(SparkIMain.scala:871) at org.apache.spark.repl.SparkIMain.interpret(SparkIMain.scala:819) Any idea what it could be?
