Once the HBase replication system is active and there's a peer (even a disabled peer) it starts retaining WALs until they have been successfully acknowledged by all peer clusters. Since the Lily Indexer for HBase makes use of the replication system to get an stream of edits, the WALs will stick around until the indexer has said it saw the edits in them.
