Hi Arvid,
I'm using flink-s3-fs-hadoop-1.9.1.jar in plugins folder. Like I said
previously, this works normally until an exception is throw inside the
sink. It will try to recover again, but sometimes doesn't recover giving
this error.
To write to S3 I use *AvroParquetWriter* with the following code:
val writer = AvroParquetWriter
.builder[GenericRecord](new Path(finalFilePath))
*Path* is from *org.apache.hadoop.fs*, the other option is to use*
org.apache.flink.formats.parquet.StreamOutputFile
*which will use flink S3 plugin, right ? Not sure how can I convert from
Path to StreamOuputFile. I know that when I've used StreamingFileSink, I
used StreamOuputFile.
