[jira] [Created] (SPARK-24320) Cannot read file names with spaces
Zachary Radtka created SPARK-24320:
--------------------------------------
Summary: Cannot read file names with spaces
Key: SPARK-24320
URL: https://issues.apache.org/jira/browse/SPARK-24320
Project: Spark
Issue Type: Bug
Components: Spark Core, SQL
Affects Versions: 2.2.0
Reporter: Zachary Radtka
I am trying to read from a file on HDFS that has space in the file name, e.g. "file 1.csv" and I get a `java.io.FileNotFoundException: File does not exist` error.
The versions of software I am using are:
* Spark: 2.2.0.2.6.3.0-235
* Scala: version 2.11.8 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_112)
As an reproducible example I have the same file in HDFS named "file.csv" and "file 1.csv":(
{code:none}
$ hdfs dfs -ls /tmp
rw-rr- 3 hdfs hdfs 441646 2018-05-18 18:45 /tmp/file 1.csv
rw-rr- 3 hdfs hdfs 441646 2018-05-18 18:45 /tmp/file.csv{code}
The following script was used to successfully read from the file that does not have a space in the name:
{code}
scala> val if1 = "/tmp/file.csv" if1: String = /tmp/file.csv scala> val origTable = spark.read.format("csv").option("header", "true").option("delimiter", ",").option("multiLine", true).option("escape", "\"").load(if1); origTable: org.apache.spark.sql.DataFrame = [DATA REDACTED] scala> origTable.take(2) res3: Array[org.apache.spark.sql.Row] = Array([DATA REDACTED])
{code}
The same script was used to try and read from the file that has a space in the name:
{code}
scala> val if2 = "/tmp/file 1.csv"
if2: String = /tmp/file 1.csv
scala> val origTable = spark.read.format("csv").option("header", "true").option("delimiter", ",").option("multiLine", true).option("escape", "\"").load(if2);
origTable: org.apache.spark.sql.DataFrame = [DATA REDACTED]
scala> origTable.take(2)

It is possible the underlying files have been updated. You can explicitly invalidate the cache in Spark by running 'REFRESH TABLE tableName' command in SQL or by recreating the Dataset/DataFrame involved.

{code}
The underlying error is `java.io.FileNotFoundException: File does not exist: /tmp/file%201.csv`. It seems that the CSV reader is URL encoding the path and hence the file is not found.
I also tested out specifying the file location in HDFS, `val if2 = "hdfs:///tmp/file 1.csv"`, and I received the same error.
I also tested to ensure that the problem does not exist with Sparks textFile reader. It had no problem reading the file:
{code:scala}
scala> sc.textFile(if2).take(2)
res5: Array[String] = Array(DATA REDACTED)
{code}
One interesting thing to note is that `printSchema` does work, but when trying to do any operation on the file, a `FileNotFoundError` occurs.
The temporary work around for this problem is removing spaces from filenames.
