--------------------------------------
Summary: Enable multi-line true could break the read csv in Azure
Data Lake Storage gen2
Key: SPARK-32206
URL: https://issues.apache.org/jira/browse/SPARK-32206
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.4.5, 2.3.2
Reporter: Qionghui Zhang
I'm using azure data lake gen2, when I'm loading data frame with certain
options:
var df = spark.read.format("csv")
.option("ignoreLeadingWhiteSpace", "true")
.option("ignoreTrailingWhiteSpace", "true")
.option("parserLib", "UNIVOCITY")
.option("multiline", "true")
.option("inferSchema", "true")
.option("mode", "PERMISSIVE")
.option("quote", "\"")
.option("escape", "\"")
.option("timeStampFormat", "M/d/yyyy H:m:s a")
.load("abfss://\{containername}@\{storage}.dfs.core.windows.net/\{DirectoryWithoutColon}")
.limit(1)
It will load data correctly.
But if I use \{DirectoryWithColon}, it will thrown error:
java.lang.IllegalArgumentException: java.net.URISyntaxException: Relative path
in absolute URI: Query.csv@snapshot=2020-07-07T07:30:12.1000093Z.
Then if I remove .option("multiline", "true"), data can be loaded, but for sure
that the dataframe is not handled correctly because there are newline character.
So I believe it is a bug.
And since our production is running correctly if we enable
spark.read.schema(\{SomeSchemaList}).format("csv"), and we want to use
inferschema feature on those file path with colon or other special characters,
could you help fix this issue?
