Hi Everyone,
We are running solr 6.4.1 in cloud mode on CentOS production server.
Currently, we are using the embedded zookeeper. It is a simple set up with
one collection and one shard.
By default, Jetty server binds to all interfaces which is not safe so we
have changed the bin/solr script. We have added "-Djetty.host=127.0.0.1" in
SOLR_START_OPTS so that it looks like as follows.
SOLR_START_OPTS=('-server' "${JAVA_MEM_OPTS[@]}" "${GC_TUNE[@]}"
"${GC_LOG_OPTS[@]}" \
"${REMOTE_JMX_OPTS[@]}" "${CLOUD_MODE_OPTS[@]}"
$SOLR_LOG_LEVEL_OPT -Dsolr.log.dir="$SOLR_LOGS_DIR" \
"-Djetty.host=127.0.0.1" "-Djetty.port=$SOLR_PORT"
"-DSTOP.PORT=$stop_port" "-DSTOP.KEY=$STOP_KEY" \
"${SOLR_HOST_ARG[@]}" "-Duser.timezone=$SOLR_TIMEZONE" \
"-Djetty.home=$SOLR_SERVER_DIR" "-Dsolr.solr.home=$SOLR_HOME"
"-Dsolr.install.dir=$SOLR_TIP" \
"${LOG4J_CONFIG[@]}" "${SOLR_OPTS[@]}")
We just found that with this change everything works fine in cloud mode
except the streaming expressions. With streaming expressions, we get
following response.
org.apache.solr.client.solrj.SolrServerException: Server refused connection
> at: http://<server ip>:8081/solr/collection1_shard1_replica1
We don't get this error if we let jetty server bind to all interfaces. Any
idea about what's the problem here?
Thanks,
Pratik
