Exception while reading csv in spark

Question

I am very new to spark. I have csv file, with 2 columns only. The csv file is large (have 30 million rows). I am trying to use spark-csv_2.10:1.2.0 to load it to dataframes.

I am using the following code:

df = sqlContext.read.load('file:///path/file_third.csv', 
                           format='com.databricks.spark.csv', 
                           header='true', 
                           inferSchema='true')

I am getting following error:

[Stage 2:>                                                         (0 + 8) / 10]16/08/04 15:32:57 ERROR Executor: Exception in task 1.0 in stage 2.0 (TID 3)
com.univocity.parsers.common.TextParsingException: Length of parsed input (1000001) exceeds the maximum number of characters defined in your parser settings (1000000). 
Identified line separator characters in the parsed content. This may be the cause of the error. The line separator in your parser settings is set to '\n'. Parsed content:

And the following hint is coming. I am guessing it is not able understand line break.

Hint: Number of characters processed may have exceeded limit of 1000000 characters per column. Use settings.setMaxCharsPerColumn(int) to define the maximum number of characters a column can have
Ensure your configuration is correct, with delimiters, quotes and escape sequences that match the input format you are trying to parse
