问题
I downloaded and unziped the titan.zip and used the command ./titan.sh -v start. Now I get the output:
./titan.sh -v start
Forking Cassandra...
OpenJDK 64-Bit Server VM warning: The UseParNewGC flag is deprecated and will likely be removed in a future release
Running nodetool statusthrift.Error: Config file not found: /usr/lib64/jvm/java-1.9.0-openjdk-1.9.0/jre/conf/management/management.properties
...... timeout exceeded (60 seconds)
See /home/hausi/Documents/titan-0.5.4-hadoop2/bin/../log/cassandra.log for Cassandra log output.
The file management.properties does not exist on my machine. I could find any information about. Is it necessary to run Titan? How can I create it?
Little of topic bonus question: Since the company behind Titan was bought, will the database developmend be stopped?
回答1:
It looks like you are running JDK9?
/usr/lib64/jvm/java-1.9.0-openjdk-1.9.0/jre/conf/management/management.properties
If I'm not misreading that, I think the answer is to downgrade to JDK7 or JDK8.
Since the company behind Titan was bought, will the database development be stopped?
The short answer is "no" and that development will continue. Please read:
