{"error":"Instantiation of [simple type, class io.druid.indexing.common.task.HadoopIndexTask] value

Hi,

I am using Druid 0.9.1.1 to index with hadoop 2.7.2 .

My primary indexing worked perfectly fine.

Now I want to perform few delta loads to few segments as we have some latency in data load.

I tried the “Reindexing and Delta Ingestion with Hadoop Batch Ingestion” ,

but it keeps on giving me

{“error”:“Instantiation of [simple type, class io.druid.indexing.common.task.HadoopIndexTask] value failed: null”}

Any help will be appreciated.

Thanks

ani

This error message could be better, but, usually it means that something required is missing from your json task spec, or that your json task spec in the wrong structure. Try double checking your json against one of the examples in the documentation.

Thanks for the quick reply. When I run the specfile without segments , it works perfectly fine. This error comes only when I am adding the segments part.

I have added the specfile here, it will be greatly appreciate if you could have a look into it and let me know what I am missing.
