gaoshu updated KAFKA-8343:
--------------------------
Description: 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, or RockesIterator.key() was accessed after RocksDBstore.close().
(was: 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})
