[jira] [Commented] (SPARK-14162) java.lang.IllegalStateException:
Did not find registered driver with class oracle.jdbc.OracleDriver
[ https://issues.apache.org/jira/browse/SPARK-14162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15265310#comment-15265310 ]
Martin Hall commented on SPARK-14162:
-------------------------------------
I got the same error when I had forgotten to copy the oracle jdbc jar file (ojdbc6.jar) to one of the spark worker nodes

> Key: SPARK-14162
> URL: https://issues.apache.org/jira/browse/SPARK-14162
> Project: Spark
> Issue Type: Bug
> Affects Versions: 1.6.1
> Reporter: Zoltan Fedor
>
> This is an interesting one.
> We are using JupyterHub with Python to connect to a Hadoop cluster to run Spark jobs and as the new Spark versions come out I compile them and add as new kernels to JupyterHub to be used.
> There are also some libraries we are using, like ojdbc to connect to an Oracle database.
> Now the interesting thing, that ojdbc worked fine in Spark 1.6.0 but suddenly "it cannot be found" in 1.6.1.
> Everything, all settings are the same when starting pyspark 1.6.1 and 1.6.0, so there is no reason for it not to work in 1.6.1 if it works in 1.6.0.
> This is the pysparjk code I am running in both 1.6.1 and 1.6.0:
> {quote}
> df = sqlContext.read.format('jdbc').options(url='jdbc:oracle:thin:'+connection_script+'', dbtable='bi.contact').load()
> print(df.count()){quote}
> And it throws this error in 1.6.1 only:

> I know that this usually means that the ojdbc driver is not available on the executor, but it is. Spark is being started the exact same way in 1.6.1 as in 1.6.0 and it does find it on 1.6.0.
> I can steadily reproduce this, so the only conclusion that something must have changed between 1.6.0 and 1.6.1 causing this, but I have see no "depreciation" notice of anything what could cause this.
