NOT_SUPPORTED

NOT_SUPPORTED

Error message

Compression extension not supported for S3 Select: ${path}

What it means

getCompressionType inspects the path's compression codec; S3 Select only supports NONE, GZIP, and BZIP2, so any other compressed file routed through S3SelectLineRecordReader is rejected as NOT_SUPPORTED.

Solutions

  1. Store the data uncompressed or as GZIP/BZIP2 for S3 Select
  2. Disable S3 Select for this format so the connector reads it directly
  3. Recompress the source files
