Examples with LayoutFeature org.apache.hadoop.hdfs.protocol.LayoutVersion.LayoutFeature used on opensource projects

Example 1 with LayoutFeature

use of org.apache.hadoop.hdfs.protocol.LayoutVersion.LayoutFeature in project hadoop by apache.

the class TestLayoutVersion method testNameNodeFeatureMinimumCompatibleLayoutVersions.

/**
   * Tests expected values for minimum compatible layout version in NameNode
   * features.  TRUNCATE, APPEND_NEW_BLOCK and QUOTA_BY_STORAGE_TYPE are all
   * features that launched in the same release.  TRUNCATE was added first, so
   * we expect all 3 features to have a minimum compatible layout version equal
   * to TRUNCATE's layout version.  All features older than that existed prior
   * to the concept of a minimum compatible layout version, so for each one, the
   * minimum compatible layout version must be equal to itself.
