Method Details

writeSequenceFile

org.apache.nifi.flowfile.FlowFile writeSequenceFile(org.apache.nifi.flowfile.FlowFile flowFile,
 org.apache.nifi.processor.ProcessSession session,
 org.apache.hadoop.conf.Configuration configuration,
 org.apache.hadoop.io.SequenceFile.CompressionType compressionType,
 org.apache.hadoop.io.compress.CompressionCodec compressionCodec)

Creates a Sequence File by writing the given FlowFile as key/value pairs. The provided FlowFile may be a package of multiple FlowFiles, or just one. The keys for the Sequence File are the flow files' logical names. The values are the flow files' content.

Parameters:

flowFile - - the FlowFile to write to the Sequence File.

session - session

configuration - configuration

compressionType - compression type

compressionCodec - compression codec

Returns:

the written to SequenceFile flow file
