I am trying to read an XML file which is 1GB is size. I am getting an
error 'java.lang.OutOfMemoryError: Requested array size exceeds VM limit'
after reading 7 partitions in local mode. In Yarn mode, it
throws 'java.lang.OutOfMemoryError: Java heap space' error after reading 3
partitions.

I see that 'ignoring namespaces' issue is resolved.

How do we enable this option and ignore namespace prefixes?

I'm trying to analyze XML documents using spark-xml package. Since all XML
columns are optional, some columns may or may not exist. When I register
the Dataframe as a table, how do I check if a nested column is existing or
not? My column name is "emp" which is already exploded and I am trying to

I'm trying to convert XML to AVRO. But, I am getting SchemaParser
exception for 'Rules' which is existing in two separate containers. Any
thoughts?
XML is attached.
df =

I started my pyspark shell with command (I am using spark 1.6).
bin/pyspark --packages graphframes:graphframes:0.1.0-spark1.6
I have copied
http://dl.bintray.com/spark-packages/maven/graphframes/graphframes/0.1.0-spark1.6/graphframes-0.1.0-spark1.6.jar
to the lib directory of Spark as well.

In Spark 2.0, DataFrames and Datasets are unified. DataFrame is simply an
alias for a Dataset of type row. I have few questions.
1) What does this really mean to an Application developer?
2) Why this unification was needed in Spark 2.0?
3) What changes can be observed in Spark 2.0 vs Spark 1.6?
Thanks Sean and Jacek.
Do we have any updated documentation for 2.0 somewhere?

Would you mind providing an approximate date of Spark 2.0 release? Is it
early May or Mid May or End of May?
Thanks,

It may be simple question...But, I am struggling to understand this
DStream is a sequence of RDDs created in a batch window. So, how do I know
how many RDDs are created in a batch?
I am clear about the number of partitions created which is
Number of Partitions = (Batch Interval /

--total-executor-cores to configure the resources allocated for each

Generally what tools are used to schedule spark jobs in production?
How is spark streaming code is deployed?
I am interested in knowing the tools used like cron, oozie etc.

for API stability as spark sql
matured out of alpha as part of 1.3.0 release.
It is forward looking and brings (dataframe like) syntax that was not
available with the older schema RDD.

Experts,
I have few basic questions on DataFrames vs Spark SQL. My confusion is
more with DataFrames.
1) What is the difference between Spark SQL and DataFrames? Are they same?
2) Documentation says SchemaRDD is renamed as DataFrame. This means
SchemaRDD is not existing in 1.3?
3) As per
