-----------------------------------------
Summary: Mongo Unit-tests not able to import properly the test
data when running in sharded mode
Key: DRILL-7269
URL: https://issues.apache.org/jira/browse/DRILL-7269
Project: Apache Drill
Issue Type: Bug
Components: Tools, Build & Test
Affects Versions: 1.17.0
Reporter: Dmytriy Grinchenko
Assignee: Dmytriy Grinchenko
Fix For: 1.17.0
The problem hiding in {{MongoTestSuit}} and the way how the data r bootstrapped
on distributed cluster start up. It looks like not all shard come online, while
we already starting to upload test data sets to DB.
The bug start appear after fixes done in DRILL-7196, where we have deployed a
sharded cluster but have used it as a single-node.
Below is an comparison of data between sharded cluster and single-mode:
{code:title=sharded}
#: full_name
0: "Mary Pierson"
1: "John Reed"
2: "Lynn Kwiatkowski"
3: "Donald Vann"
4: "Judy Owens"
5: "Lori Lightfoot"
{code}
{code:title=single}
