Options.ChecksumCombineMode (Apache Hadoop Main 3.5.0 API)
Description: declaration: package: org.apache.hadoop.fs, class: Options, enum: ChecksumCombineMode

Package org.apache.hadoop.fs

# Enum Class Options.ChecksumCombineMode

java.lang.Object
java.lang.Enum<Options.ChecksumCombineMode>
org.apache.hadoop.fs.Options.ChecksumCombineMode

All Implemented Interfaces:
  `Serializable`, `Comparable<Options.ChecksumCombineMode>`, `Constable`

Enclosing class:
  Options

public static enum Options.ChecksumCombineMode extends Enum<Options.ChecksumCombineMode>
Enum for indicating what mode to use when combining chunk and block checksums to define an aggregate FileChecksum. This should be considered a client-side runtime option rather than a persistent property of any stored metadata, which is why this is not part of ChecksumOpt, which deals with properties of files at rest.
