Examples with StoreFile org.apache.hadoop.hbase.shaded.protobuf.generated.SnapshotProtos.SnapshotRegionManifest.StoreFile used on opensource projects

Example 1 with StoreFile

use of org.apache.hadoop.hbase.shaded.protobuf.generated.SnapshotProtos.SnapshotRegionManifest.StoreFile in project hbase by apache.

the class FileArchiverNotifierImpl method bucketFilesToSnapshot.

/**
 * For the given snapshot, find all files which this {@code snapshotName} references. After a file
 * is found to be referenced by the snapshot, it is removed from {@code filesToUpdate} and
 * {@code snapshotSizeChanges} is updated in concert.
 *
 * @param snapshotName The snapshot to check
 * @param filesToUpdate A mapping of archived files to their size
 * @param snapshotSizeChanges A mapping of snapshots and their change in size
