Anistojoseph opened a new issue, #16573:
URL: https://github.com/apache/druid/issues/16573
Please provide a detailed title (e.g. "Broker crashes when using TopN query
with Bound filter" instead of just "Broker crashes").
### Affected Version
We observed the issue from Druid version 26.0.0 and the same issue is there
on the latest version which is 29.0.1
on Version 0.22.1 we are not seeing this issue.
### Description
we encountering an issue when trying to parse the ORC file created from a
Hive external table on Druid version 27.0.0. The error message "Failed to
sample data: Unhandled type: COMPLEX" is displayed. However, I can load the
data into the cluster using the pre-created JSON spec, and the data is being
received correctly. The error only occurs during the Parse data step.
Interestingly, I can parse the same file on Druid version 0.22.1.
(The JSON spec used to load the data on version 27 was created from version
0.22.1)
we have also tried the latest version (29.0.1)of Druid, but we are still
encountering the same error.
in this case it is an issue with the date type. our ORC reader returns it
as a Joda DateTime object. our auto type detection code is not able to figure
out what to do with this. the type detection code is expecting to see more
primitive types like strings, numbers, & arrays. what changed in recent druid
versions is that the sampler started using auto type detection.
