[SPARK-8437] [DOCS] Corrected: Using directory path without wildcard for filename slow for large number of files with wholeTextFiles and binaryFiles Note that 'dir/*' can be more efficient in some Hadoop FS implementations that 'dir/' (now fixed scaladoc by using HTML entity for *) Author: Sean Owen <[email protected]> Closes #7126 from srowen/SPARK-8437.2 and squashes the following commits: 7bb45da [Sean Owen] Note that 'dir/*' can be more efficient in some Hadoop FS implementations that 'dir/' (now fixed scaladoc by using HTML entity for *) Project: http://git-wip-us.apache.org/repos/asf/spark/repo Commit: http://git-wip-us.apache.org/repos/asf/spark/commit/ada384b7 Tree: http://git-wip-us.apache.org/repos/asf/spark/tree/ada384b7 Diff: http://git-wip-us.apache.org/repos/asf/spark/diff/ada384b7 Branch: refs/heads/master Commit: ada384b785c663392a0b69fad5bfe7a0a0584ee0 Parents: 689da28 Author: Sean Owen <[email protected]> Authored: Tue Jun 30 10:07:26 2015 -0700 Committer: Andrew Or <[email protected]> Committed: Tue Jun 30 10:07:26 2015 -0700 ---------------------------------------------------------------------- core/src/main/scala/org/apache/spark/SparkContext.scala | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/spark/blob/ada384b7/core/src/main/scala/org/apache/spark/SparkContext.scala ---------------------------------------------------------------------- diff --git a/core/src/main/scala/org/apache/spark/SparkContext.scala b/core/src/main/scala/org/apache/spark/SparkContext.scala index b3c3bf3..0e5a86f 100644 --- a/core/src/main/scala/org/apache/spark/SparkContext.scala +++ b/core/src/main/scala/org/apache/spark/SparkContext.scala @@ -831,7 +831,8 @@ class SparkContext(config: SparkConf) extends Logging with ExecutorAllocationCli * }}} * * @note Small files are preferred, large file is also allowable, but may cause bad performance. - * + * @note On some filesystems, `.../path/*` can be a more efficient way to read all files + * in a directory rather than `.../path/` or `.../path` * @param minPartitions A suggestion value of the minimal splitting number for input data. */ def wholeTextFiles( @@ -878,9 +879,10 @@ class SparkContext(config: SparkConf) extends Logging with ExecutorAllocationCli * (a-hdfs-path/part-nnnnn, its content) * }}} * - * @param minPartitions A suggestion value of the minimal splitting number for input data. - * * @note Small files are preferred; very large files may cause bad performance. + * @note On some filesystems, `.../path/*` can be a more efficient way to read all files + * in a directory rather than `.../path/` or `.../path` + * @param minPartitions A suggestion value of the minimal splitting number for input data. */ @Experimental def binaryFiles( --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
