there is the need to give correct path to README.md
so correct code is:
lines = sc.textFile("../README.md")
lines.count()

An error occurred while calling o590.save. : java.lang.RuntimeException: quote cannot be more than one character

When I use pyspark to write to the csv file:
sql_df.write\

.save(output)
a problem occurs:

Well it's just like the error says it's not accepting your unicode as a single character. use "" instead for null value.

Apache Spark Exception: FileAlreadyExistsException: Operation failed: "The specified path already exists."

I’m facing errors while writing parquet data to some temporary folder in ADLS-GEN2.
My folder ‘X’ has parquet files Partitioned with YYYY MM DD sub folders. I have loaded entire data from ‘X’ folder to a dataframe and tried to write the data from dataframe to some temporary folder ‘y’ in ADLS gen2 using simple command below. But writing to folder ‘y’ is failing with below error. Any help/suggestions greatly appreciated .
WriteCommand:
Folder_x_df.write.mode("overwrite")
.option("header","true")
.parquet(folder_y_path)

Is it possible to run Spark jobs (like the WordCount sample) in the local mode on Cygwin?

I am executing a simple Spark code for reading a file from local system but getting error below is the code on Cygwin console :
val orders = sc.textFile("C:///DataResearch/retail_db/orders")
orders.first()
after executing orders.first() I am getting below error :

Cannot use Scala Worksheet after update

After a recent update for ScalaIDE, I cannot open any existing worksheet nor creating new worksheet.
The error message is
Plug-in org.scalaide.worksheet was unable to load class org.scalaide.worksheet.editor.ScriptEditor.
I am experiencing this problem both on Mac (Yosemite) and Ubuntu 14.04.
I am using:
Eclipse Luna
Java 8
Scala 2.11.2
Scala IDE 4.0.0 Release Candidate 1! (4.4)
Any help is appreciated.
Here is the error detail
org.eclipse.core.runtime.CoreException: Plug-in org.scalaide.worksheet was unable to load class org.scalaide.worksheet.editor.ScriptEditor.
