----------------------------------------
Summary: Repeated incremental nodetool repair results in failed
repairs due to running anticompaction
Key: CASSANDRA-9097
URL: https://issues.apache.org/jira/browse/CASSANDRA-9097
Project: Cassandra
Issue Type: Bug
Reporter: Gustav Munkby
Priority: Minor
I'm trying to synchronize incremental repairs over multiple nodes in a
Cassandra cluster, and it does not seem to easily achievable.
In principle, the process iterates through the nodes of the cluster and
performs `nodetool -h $NODE repair --incremental`, but that sometimes fails on
subsequent nodes. The reason for failing seems to be that the repair returns as
soon as the repair and the _local_ anticompaction has completed, but does not
guarantee that remote anticompactions are complete. If I subsequently try to
issue another repair command, they fail to start (and terminate with failure
after about one minute). It usually isn't a problem, as the local
anticompaction typically involves as much (or more) data as the remote ones,
but sometimes not.
