-----------------------------------------
Summary: Cannot call sqlContext inside udf
Key: SPARK-17735
URL: https://issues.apache.org/jira/browse/SPARK-17735
Project: Spark
Issue Type: Bug
Components: Spark Core, SQL
Affects Versions: 1.6.0
Environment: Linux
Reporter: Saif Addin Ellafi
Priority: Minor
Hello, I know it is a strange use case but I just wanted to append is cache to
hive tables and turned out into this
def inCacheUdf = org.apache.spark.sql.functions.udf {name: String =>
sqlContext.isCached(name)}
val ts = sqlContext.tables
ts.withColumn("foo", inCacheUdf(ts.col("tableName"))).show
.. will throw a Null Pointer Exception.
I am not sure, since in my program I was getting:
A master url must be set in your configuration
or NullPointer a getConf as well.
Thoughts?
