JavaRDD<String> textFile (String path, int minPartitions) textFile () method reads a text file from HDFS/local file system/any hadoop supported file system URI into the number of partitions specified and returns it as an RDD of Strings. Unlike the createOrReplaceTempView command, Instead of using read API to load a file into DataFrame and query it, you can also query that When you have a column with a delimiter that used to split the columns, usequotesoption to specify the quote character, by default it is and delimiters inside quotes are ignored. Let's assume your CSV content looks like the following: Let's change the read function to use the default quote character '"': It doesn't read the content properly though the record count is correct: To fix this, we can just specify the escape option: It will output the correct format we are looking for: If you escape character is different, you can also specify it accordingly. Using these methods we can also read all files from a directory and files with a specific pattern.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[320,50],'sparkbyexamples_com-box-3','ezslot_6',105,'0','0'])};__ez_fad_position('div-gpt-ad-sparkbyexamples_com-box-3-0');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[320,50],'sparkbyexamples_com-box-3','ezslot_7',105,'0','1'])};__ez_fad_position('div-gpt-ad-sparkbyexamples_com-box-3-0_1'); .box-3-multi-105{border:none !important;display:block !important;float:none !important;line-height:0px;margin-bottom:7px !important;margin-left:auto !important;margin-right:auto !important;margin-top:7px !important;max-width:100% !important;min-height:50px;padding:0;text-align:center !important;}.

For example, let's assume the field is quoted with double double quotes: We will encounter one error if we use the following code to read it: java.lang.RuntimeException: quote cannot be more than one character. Bucketing and sorting are applicable only to persistent tables: while partitioning can be used with both save and saveAsTable when using the Dataset APIs. Sets a single character used for escaping quoted values where the separator can be part of the value. Sets the string representation of a non-number value. sparkContext.wholeTextFiles() reads a text file into PairedRDD of type RDD[(String,String)] with the key being the file path and value being contents of the file. Using these we can read a single text file, multiple files, and all files from a directory into Spark DataFrame and Dataset. CSV built-in functions ignore this option. A little overkill but hey you asked.
