Example 13 with RegionInfo

use of org.apache.hadoop.hbase.client.RegionInfo in project hbase by apache.

the class AssignmentManager method markRegionAsMerged.

/**

 * unassigned and the above markRegionClosed has been called on each so they have been
 * disassociated from a hosting Server. The merged region will be open after this call. The
 * merged regions are removed from hbase:meta below. Later they are deleted from the filesystem
 * by the catalog janitor running against hbase:meta. It notices when the merged region no
 * longer holds references to the old regions (References are deleted after a compaction
 * rewrites what the Reference points at but not until the archiver chore runs, are the
 * References removed).
