Alex S commented on SPARK-19340:
--------------------------------
Looks like the error happens when spark tries to infers a schema from the file,
which happens in csv case. If you configure user-defined schema it should work.
I haven't tried it with hdfs though.
{code}
spark.read.option("header","false").schema(customSchema).csv("<your
path>/test*.txt")
{code}
customSchema - is the schema you define for your csv file.

> Key: SPARK-19340
> URL: https://issues.apache.org/jira/browse/SPARK-19340
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0, 2.0.1, 2.1.0, 2.2.0
> Reporter: Reza Safi
> Priority: Minor
>
> If you want to open a file that its name is like {noformat} "*{*}*.*"
> {noformat} or {noformat} "*[*]*.*" {noformat} using CSV format, you will get
> the "org.apache.spark.sql.AnalysisException: Path does not exist" whether the
> file is a local file or on hdfs.
> This bug can be reproduced on master and all other Spark 2 branches.
> To reproduce:
> # Create a file like "test{00-1}.txt" on a local directory (like in
> /Users/reza/test/test{00-1}.txt)
> # Run spark-shell
> # Execute this command:
> {noformat}
> val df=spark.read.option("header","false").csv("/Users/reza/test/*.txt")
> {noformat}
> You will see the following stack trace:
> {noformat}
> org.apache.spark.sql.AnalysisException: Path does not exist:
> file:/Users/reza/test/test\{00-01\}.txt;
