gaoshu updated KAFKA-8343: -------------------------- Attachment: (was: fullsizeoutput_1.jpeg) > streams application crashed due to rocksdb > ------------------------------------------ > > Key: KAFKA-8343 > URL: https://issues.apache.org/jira/browse/KAFKA-8343 > Project: Kafka > Issue Type: Bug > Components: streams > Affects Versions: 1.0.0 > Environment: centos 7 jdk8 kafka-streams1.0 > Reporter: gaoshu > Priority: Major > > my streams application always crashed in few days. The crash log looks like > [https://github.com/facebook/rocksdb/issues/5234|[https://github.com/facebook/rocksdb/issues/5234].] > so I think it may because of RocksDBStore.java closed incorrectly in > multithread. I look through the below code, it means the db.close() should > after openiterators.close(). However, db.close() may be executed before > iterators.close() due to instructions reorder. I hope my guess is correct. > {code:java} > // RocksDBStore.java > @Override > public synchronized void close() { > if (!open) { > return; > } > open = false; > closeOpenIterators(); > options.close(); > wOptions.close(); > fOptions.close(); > db.close(); > options = null; > wOptions = null; > fOptions = null; > db = null; > } > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
