Hello,
I’ve just fresh installed couchbase server community version on single CentOS 6 host with couchbase Java SDK v2.3.4.
long story short,
I’ve connected to couchbase server successfully with following code:
couchbaseEnvironment = DefaultCouchbaseEnvironment.builder().build();
cluster = CouchbaseCluster.create(couchbaseEnvironment, hosts);
bucket = cluster.openBucket(CB_INFO.BUCKET_NAME);
and I’ve done nothing after that.
after connecting to the server, log says,
2016-10-12 16:58:58.124 [INFO ] SLMain::main(42) - COUCHBASE::CONNECTION::INITIALIZED
2016-10-12 16:58:58.264 [INFO ] SLMain::run(68) - CONNECTION::COUCHBASE(OK)

2016-10-12 16:59:18.265 [INFO ] SLMain::run(68) - CONNECTION::COUCHBASE(OK)
as you can see, configuration provider keeps receiving “outdated configuration” every 10 seconds.
I have no idea why this happens and yet know the effects.
I’ve tried changing all the environment configurations and sdk versions from 2.0 to 2.3 but the results are the same.
I don’t know what to do and what should do.
has anybody experienced this? or have solution to this?
EDIT: adding trace logs
