Hello, we have a problem with configuring RocksDB as a key-value store with our Samza 0.9.0 project. We added this line to our config:
stores.my-store.factory=org.apache.samza.storage.kv.RocksDbKeyValueStorageEngineFactory But then our Samza job couldn't locate the RocksDbKeyValueStorageEngineFactory class. So we added compile "org.apache.samza:samza-kv-rocksdb_2.10:$samzaVersion" to our gradle build script. It helped but now Samza failed to start because it couldn't find librocksdbjni-linux64.so library. We added export ROCKSDB_SHAREDLIB_DIR=/opt/samza/lib to our init script and it didn't help. Then we manually copied the librocksdbjni-linux64.so from the rocksdbjni-3.5.1.jar to the /opt/samza/lib folder and Samza still couldn't start, now because of 2015-11-09T14:35:06,209 INFO [main] org.apache.samza.container.SamzaContainer$ - Got store consumers: Map(tracking-info -> org.apache.samza.system.kafka.KafkaSystemConsumer@78461bc4) # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x0000003c4de092ab, pid=4410, tid=139728971949824 And we're out of ideas at the moment. Can you please help me set up RocksDB correctly? I suppose we are doing something completely wrong. Is it possibble to use another key-value store at least? Lukáš Havrlant
