Cloudera, BigData, Semantic IoT, Hadoop, NoSQL

Cloudera CDH/CDP 및 Hadoop EcoSystem, Semantic IoT등의 개발/운영 기술을 정리합니다. gooper@gooper.com로 문의 주세요.


오류내용#1처럼 fuseki endpoint를 통하여 요청을 보낼때 순간적으로 많은 요청이 발생하면 많은양의 소켓케넥션이 TIME-WAIT상태(netstat -a | grep 사용포트(예,23030))가 되면서 오류가 발생할 수 있는데 이럴때는

echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse
and/or
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle
를 수행하여 TIME-WAIT상태의 소켓 커넥션을 재사용할 수 있도록 설정해준다.

이렇게 처리해주면 오류내용#2가 발생하는데 이는 커넥션 재사용에 커넥션은 형성되었는데 이를 jena가 처리하지 못하는 과부하 상태를 의미한다.
