Hi there, The tutorial you’re reading there was written before the merge of SparkR for Spark 1.4.0 For the merge, the RDD API (which includes the textFile() function) was made private, as the devs felt many of its functions were too low level. They focused instead on finishing the DataFrame API which supports local, HDFS, and Hive/HBase file reads. In the meantime, the devs are trying to determine which functions of the RDD API, if any, should be made public again. You can see the rationale behind this decision on the issue’s JIRA [1].
You can still make use of those now private RDD functions by prepending the function call with the SparkR private namespace, for example, you’d use SparkR:::textFile(…). Hope that helps, Alek [1] -- https://issues.apache.org/jira/browse/SPARK-7230 From: Wei Zhou <zhweisop...@gmail.com<mailto:zhweisop...@gmail.com>> Date: Thursday, June 25, 2015 at 3:33 PM To: "user@spark.apache.org<mailto:user@spark.apache.org>" <user@spark.apache.org<mailto:user@spark.apache.org>> Subject: sparkR could not find function "textFile" Hi all, I am exploring sparkR by activating the shell and following the tutorial here https://amplab-extras.github.io/SparkR-pkg/<https://urldefense.proofpoint.com/v2/url?u=https-3A__amplab-2Dextras.github.io_SparkR-2Dpkg_&d=AwMFaQ&c=NRtzTzKNaCCmhN_9N2YJR-XrNU1huIgYP99yDsEzaJo&r=0vZw1rBdgaYvDJYLyKglbrax9kvQfRPdzxLUyWSyxPM&m=aL4A2Pv9tHbhgJUX-EnuYx2HntTnrqVpegm6Ag-FwnQ&s=qfOET1UvP0ECAKgnTJw8G13sFTi_PhiJ8Q89fMSgH_Q&e=> And when I tried to read in a local file with textFile(sc, "file_location"), it gives an error could not find function "textFile". By reading through sparkR doc for 1.4, it seems that we need sqlContext to import data, for example. people <- read.df(sqlContext, "./examples/src/main/resources/people.json", "json" ) And we need to specify the file type. My question is does sparkR stop supporting general type file importing? If not, would appreciate any help on how to do this. PS, I am trying to recreate the word count example in sparkR, and want to import README.md file, or just any file into sparkR. Thanks in advance.
