Summary: MongoDB adapter tutorial is out of date
Key: CALCITE-2734
URL: https://issues.apache.org/jira/browse/CALCITE-2734
Project: Calcite
Issue Type: Improvement
Components: avatica, mongodb
Affects Versions: 1.17.0
Environment: Host: Mac OS 10.14.1
Calcite: Master
Reporter: TommyLike
Hey all,
I am trying to learn Calcite via MongoDB adapter, and I found there is a
related tutorial section in
[HOWTO|[https://calcite.apache.org/docs/howto.html#mongodb-adapter]|https://calcite.apache.org/docs/howto.html#mongodb-adapter],].
But it seems to be a little out of date now, I found several issues at least:
1. model file: *mongo-zips-model.json* has been renamed into
*mongo-models.json.*
2. data source file *zips.json* doesn't include all the data required in the
models.json file.
3. the MongoDB adapter can not be directly used, because there is a log related
bug when execute command ``!connect
jdbc:calcite:model=mongodb/target/test-classes/mongo-model.json admin admin``,
related output:
```
SLF4J: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class
path, preempting StackOverflowError.
SLF4J: See also [http://www.slf4j.org/codes.html#log4jDelegationLoop] for more
details.
Caused by: java.lang.NoClassDefFoundError: Could not initialize class
org.apache.log4j.Log4jLoggerFactory
```
