Spark - PySpark sql error
<p>I have a simple pyspark code but i can't run it. I try to run it on Ubuntu system and I use PyCharm IDE. I would like to connect to Oracle XE Database and I want to print my test table. </p>

<p>Here comes my spark python code: </p>

<pre><code>from pyspark import SparkContext
from pyspark.sql import SQLContext

sc = SparkContext()

sqlContext = SQLContext(sc)

demoDf = sqlContext.read.format("jdbc").options(
    url="jdbc:oracle:thin:@10.10.10.10:1521:XE",
    driver="oracle.jdbc.driver.OracleDriver",
    table="tst_table",
    user="xxx",
    password="xxx").load()

demoDf.show()
</code></pre>

<p>And this is my trace:</p>

<p>Can Anybody help me? </p>

<p>Change to <code>dbtable</code> from <code>table</code> like this,</p>

<pre><code>demoDf = sqlContext.read.format("jdbc").options(
    url="jdbc:oracle:thin:@10.10.10.10:1521:XE",
    driver="oracle.jdbc.driver.OracleDriver",
    dbtable="tst_table",
    user="xxx",
    password="xxx").load()
</code></pre>

python apache-spark pyspark
