Hi all,
I am using the code below to get the replica state:
ZkStateReader reader = cloudSolrClient.getZkStateReader();
ClusterState slices22 = reader.getClusterState();
DocCollection slices =
reader.getClusterState().getCollection(collection);
Iterator<Slice> iter = slices.iterator();
while (iter.hasNext()) {
Slice slice = iter.next();
for(Replica replica:slice.getReplicas()) {
System.out.println(replica.getStr( "state" ));
}
}
question is I can manage to get the correct replica state if I start and
stop solr using command line.
how if solr failure or crashed, how can I get the correct replica state?
regards,
yy
