@diana.arnos: hey there :wave:
I'm not able to make partial upserts work on 0.9.0 and the error messages are not helpful.
the partial upserts did work previously, I have no idea what is happening.
Can someone help me? This kinda blocks me to deliver my app to prod :sob:
More info (such as config files and error messages) .
@mayanks: @jackie.jxt just fixed an issue in master, so adding him to the thread

@nair.a: Hi Team,
We have configured HDFS as deep storage for pinot cluster.
Upon checking the segment.realtime.download.url , it is pointing to controllers storage path
Url:
returned Path: /tmp/data/PinotController/max_reporting_aggregations/max_reporting_aggregations__0__150__20211127T0641Z
*Shouldn't this segment get stored at HDFS location?*
Below are the controller's and server's config.
Controller Config:
```# Pinot Role
pinot.service.role=CONTROLLER
# Pinot Cluster name
pinot.cluster.name=MAX-Pinot
# Pinot Zookeeper Server
pinot.zk.server=c81:2181
# Use hostname as Pinot Instance ID other than IP
pinot.set.instance.id.to.hostname=true
# Pinot Controller Port
controller.port=9000
# Pinot Controller VIP Host

# Pinot Controller VIP Port
controller.vip.port=9000
# Location to store Pinot Segments pushed from clients

controller.local.temp.dir=/opt/pinot/host/
controller.enable.split.commit=true

Server Config:
```# Pinot Role

@mayanks: The download url should point to HDFS path. Can you check if PinotFS is initialized to HDFS in controller logs?
@tiger: Hi, I'm trying to use the Trino/Pinot connector but I'm seeing some strange behavior.
Queries such as `select * from pinot.default.table` seem to just run forever without returning any results.
But queries like `select max(col) from pinot.default.table` seem to run fine. It looks like I have to do some sort of aggregation or group by in order for the query to run. I can't seem to just select rows. Is this behavior expected?
@mayanks: @xiangfu0 ^^
@xiangfu0: have you tried ran with a limit X for your select * query?
@tiger: yep I've tried with a limit
@tiger: As another example:
`select col from pinot.default.table limit 10` seems to run forever without returning.
`select col from pinot.default.table group by col limit 10` works
@tiger: Actually this seems to be fixed after upgrading trino
