Index_parallel type failed to ingest data

Hi Team,
I’m trying to ingest data in druid with “index_parallel” type but I’m getting error :

{“error”:“Could not resolve type id ‘index_parallel’ into a subtype of [simple type, class io.druid.indexing.common.task.Task]\n at [Source: HttpInputOverHTTP@5774dbdd[c=2631,q=1,[0]=EOF,s=STREAM]; line: 1, column: 4]”}

Same index configuration works well for same data if I change index_parallel to index

In my case, we are loading good amount of data in to druid - 15 nodes cluster. and need to verify parallelism for multiple middle manager.

Any idea/help would be really appreciated !!!



I’m using druid : 0.12.3 with 15 nodes cluster

Hey Kiran,

Parallel native indexing was only made available in 0.13 which hasn’t been fully released yet.

See the following release notes:

Alternative you can look at hadoop batch ingestion in 0.12.3.

Best regards,


Hi Dylan,
Appreciated your feedback, basically I’d like to run multiple index ingestion job on druid 15 nodes cluster, but I’m getting error for one of job every time.
