If the system is reporting files that need to be replicated, it's
probably one of two problems:
* The WALs are still in use by the TabletServers. In its current
implementation, the WALs are not replicated until the TabletServers
don't referenced those WALs. This happens either by writing enough data
or when the tabletserver is restarted. You can try to investigate either
for this.
* The replication is trying to happen but fails. You can look at the
TabletServer logs on the primary instance to see if there are any
reported exceptions around sending the data to the peer.

Hi,
I've configured replication between two instances of accumulo: one is
the primary accumulo and the other is a peer created from a restore of
the backup of the primary.
I've followed the instructions in the manual
(https://accumulo.apache.org/1.7/accumulo_user_manual#_replication)
and I can see the 4 tables I've configured to replicate in the
Accumulo Monitor but they do not replicate. They have 1 or 2 "Files
needing replication" and this number never decreases.
I've also tried inserting data in one of the tables and the data does
not replicate to the accumulo peer instance.
In the master log I see many entries like this one:
2017-12-29 13:22:25,490 [replication.RemoveCompleteReplicationRecords]
INFO : Removed 0 complete replication entries from the table
accumulo.replication
Does anyone know what could be happening?
Thanks.
