------------------------------------
Summary: ParquetFileFormat fails to read column named with invalid
characters
Key: SPARK-27442
URL: https://issues.apache.org/jira/browse/SPARK-27442
Project: Spark
Issue Type: Bug
Components: Input/Output
Affects Versions: 2.4.1, 2.0.0
Reporter: Jan Vršovský
When reading a parquet file which contains characters considered invalid, the
reader fails with exception:
Name: org.apache.spark.sql.AnalysisException
Message: Attribute name "..." contains invalid character(s) among "
,;{}()\n\t=". Please use alias to rename it.
Spark should not be able to write such files, but it should be able to read it
(and allow the user to correct it). However, possible workarounds (such as
using alias to rename the column, or forcing another schema) do not work, since
the check is done on the input.
(Possible fix: remove superficial
{{ParquetWriteSupport.setSchema(requiredSchema, hadoopConf)}} from
{{buildReaderWithPartitionValues}} ?)
