Pyspark Size exceeds Integer.MAX_VALUE - apache-spark

i want to write a dataframe partitionned :
df.repartition(50).write.mode('overwrite').format("com.databricks.spark.avro").save(data_path)
I chose 50 partitions because the data are light, when everything works well there are 1.7MB per .avro file, so i don't understand why sometimes it fails with this error 'Pyspark Size exceeds Integer.MAX_VALUE'
The files have never reached more than 3mb.
The Exception :

Greenplum-Spark-Connector java.util.NoSuchElementException: None.get

My work Envorinments like bellow:
. Hadoop 2.7.2
. Spark 2.3.0
. Greenplum 6.8.1 <- I knew this version is latest.
and I have to create dataframe(RDD) from GPDB table. so, I have knew a "Greenplum-spark-connector". An architecture sounds good. but It does not work.
I tried like this:

The Greenplum Spark Connector version 1.6.2 is incompatible with Greenplum versions 6.7.1+. Currently we don't offer a connector for those versions of Greenplum. We'll be releasing a new Greenplum Spark Connector that supports all versions of Greenplum in the near future.

Use case-sensitive partitionColumn in Spark JDBC

When accessing to a Postgresql using the JDBC Datasource of Spark, the property partitionColumn is used as case-insensitive and a exception is thrown
CREATE TABLE data USING org.apache.spark.sql.jdbc OPTIONS (url 'jdbc:postgresql://localhost:5432/postgres', dbtable 'public.datios', lowerBound '0', upperBound '10', partitionColumn 'COD_PERSON', numPartitions '4')
Therefore, executing the query:
SELECT * FROM data
throws the next exception:
Job aborted due to stage failure: Task 1 in stage 9.0 failed 1 times, most recent failure: Lost task 1.0 in stage 9.0 (TID 19, localhost, executor driver): org.postgresql.util.PSQLException: ERROR: column "cod_person" does not exist

Is there any workaround to use a column name in uppercase to use it as the partitionColumn?

Try enclosing your column name in back-ticks to make it case sensitive.
..partitionColumn `COD_PERSON`

Spark Will Not Load Large MySql Table: Java Communications link failure - Timing Out

I'm trying to get a pretty large table from mysql so I can manipulate using spark/databricks. I can't get it to load into spark - I have tried taking smaller subsets, but even at the smallest reasonable unit, it still fails to load.
I have tried playing with the wait_timeout and interactive_timeout in mysql, but it doesn't seem to make any difference
I am also loading a smaller (different) table, and that loads just fine.
df_dataset = get_jdbc('raw_data_load', predicates=predicates).select('field1','field2', 'field3','date')
df_dataset = df_dataset.repartition('date')
df_dataset.registerTempTable('raw_data')
I then am trying to cache the data for sql purposes using
%sql
cache table raw_data;
And it goes and chugs for a while and his the database, but always times out after 30-40 minutes and I get the error below
Up until the point it times out, I see
Error in SQL statement: SparkException: Job aborted due to stage failure: Task 0 in stage 30.0 failed 4 times, most recent failure: Lost task 0.3 in stage 30.0 (TID 17075, 10.200.240.63, executor 1): com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

With extremely large tables you're going to want to partition the query across your executors. By default the JDBC reader will read the query the parallelize it from the driver. If you have an incrementing, sequential key in the table you can parallelize using the lowerBound, upperBound, and numPartitions parameters. Here's an example taken from https://docs.databricks.com/spark/latest/data-sources/sql-databases.html#python-example
df = spark.read.\
jdbc(url=jdbcUrl, \
table='employees',\
column='emp_no',\
lowerBound=1,\
upperBound=100000, \
numPartitions=100)
df.show()
Having said that, you may want to read and write the data out to Parquet as that will perform better than re-reading from JDBC again.

Can't run GraphX ConnectedComponents on spark 1.5.1 with large data (~4TB)

While trying to run a spark job with spark 1.5.1, using the following paramters:
--master "yarn"
--deploy-mode "cluster"
--num-executors 200
--driver-memory 14G
--executor-memory 14G
--executor-cores 1
Trying to run graphX ConnectedComponent on large data (~4TB) using the following commands:
System.setProperty("spark.serializer", "org.apache.spark.serializer.KryoSerializer")
val edges = …
val graph = Graph.fromEdgeTuples(edges,0,edgeStorageLevel = StorageLevel.MEMORY_AND_DISK, vertexStorageLevel = StorageLevel.MEMORY_AND_DISK)
val components = graph.connectedComponents().vertices
Some of the tasks complete successfully, and some fail with the following errors:
