> Key: DRILL-4307
> URL: https://issues.apache.org/jira/browse/DRILL-4307
> Project: Apache Drill
> Issue Type: Bug
> Components: Storage - MongoDB
> Affects Versions: 1.5.0
> Reporter: Michael Gokhman
> Priority: Major
>
> in Drill 1.4, SELECT-ing an _id results in:
> {code}
> {"$oid":"567ff2697f2310849fea0666"}
> {code}
> as expected.
> however, when working with the master branch, SELECT-ing an _id results in a
> something that looks like a pointer:
> {code}
> [B@3149a…]
> {code}
> This is caused by DRILL-3478, and can be avoided by disabling the new BSON
> record reder:
> {code:sql}
> ALTER SESSION SET store.mongo.bson.record.reader = false
> {code}
