----------------------------
Sprint: Spark 1.5 doc/QA sprint
> Cannot insert into a table using pySpark
> ----------------------------------------
>
> Key: SPARK-9714
> URL: https://issues.apache.org/jira/browse/SPARK-9714
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Yun Park
> Assignee: Yin Huai
> Priority: Blocker

> This is a bug on the master branch. After creating the table ("yun" is the
> table name) with the corresponding fields, I ran the following command.
> {code}
> from pyspark.sql import *
> sc.parallelize([Row(id=1, name="test",
> description="")]).toDF().write.mode("append").saveAsTable("yun")
> {code}
> I get the following error:
> {code}
> Py4JJavaError: An error occurred while calling o100.saveAsTable.
