Examples of MergeInfo

org.apache.accumulo.server.master.state.MergeInfo
Information about the current merge/rangeDelete. Writable to serialize for zookeeper and the Tablet

org.apache.lucene.store.MergeInfo

A MergeInfo provides information required for a MERGE context. It is used as part of an {@link IOContext} in case of MERGE context.

    defaultTablet.put(Constants.METADATA_CURRENT_LOCATION_COLUMN_FAMILY, new Text("123456"), new Value("127.0.0.1:1234".getBytes()));
