-----------------------------
Summary: 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
Attachments: fullsizeoutput_1.jpeg
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}
