> {code:java}
> java.lang.UnsupportedOperationException: Complex types not supported. at org.apache.flink.formats.parquet.vector.ParquetColumnarRowSplitReader.checkSchema(ParquetColumnarRowSplitReader.java:226) at org.apache.flink.formats.parquet.vector.ParquetColumnarRowSplitReader.<init>(ParquetColumnarRowSplitReader.java:144) at org.apache.flink.formats.parquet.vector.ParquetSplitReaderUtil.genPartColumnarRowReader(ParquetSplitReaderUtil.java:131) at org.apache.flink.formats.parquet.ParquetFileSystemFormatFactory$ParquetInputFormat.open(ParquetFileSystemFormatFactory.java:204) at org.apache.flink.formats.parquet.ParquetFileSystemFormatFactory$ParquetInputFormat.open(ParquetFileSystemFormatFactory.java:159) at org.apache.flink.streaming.api.functions.source.InputFormatSourceFunction.run(InputFormatSourceFunction.java:85) at org.apache.flink.streaming.api.operators.StreamSource.run(StreamSource.java:100) at org.apache.flink.streaming.api.operators.StreamSource.run(StreamSource.java:63) at org.apache.flink.streaming.runtime.tasks.SourceStreamTask$LegacySourceFunctionThread.run(SourceStreamTask.java:201)
> {code}
> Then I found the description in official document
>
> `File system sources for streaming is still under development. In the future, the community will add support for common streaming use cases, i.e., partition and directory monitoring.`
> means that read from flilesystem is not supported currently.
> But the above exception make users confused.If there is a msg about reading from filesystem is unsupported will be friendly.
