Reindexing Task Fails

Hi All, We’re trying to create a new hourly datasource and getting errors from the indexing service when trying to reindex. This is the error we’re getting:

HTTP ERROR: 500

Problem accessing /druid/indexer/v1/task. Reason:

javax.servlet.ServletException: com.fasterxml.jackson.databind.JsonMappingException: Instantiation of [simple type, class io.druid.indexing.common.task.IndexTask] value failed: null

And this is the spec we’re using:

{

“type”: “index”,

“spec”: {

“dataSchema”: {

“dataSource”: “web-firehose-hour”,

“metricsSpec”: [

{

“type”: “count”,

“name”: “count”

},

{

“type”: “hyperUnique”,

“name”: “unique”,

“fieldName”: “unique”

},

{

“type”: “longSum”,

“name”: “audience”,

“fieldName”: “audience”

},

{

“type”: “longSum”,

“name”: “newAudience”,

“fieldName”: “newAudience”

},

{

“type”: “doubleSum”,

“name”: “valueSum”,

“fieldName”: “valueSum”

},

{

“type”: “doubleMin”,

“name”: “valueMin”,

“fieldName”: “valueMin”

},

{

“type”: “doubleMax”,

“name”: “valueMax”,

“fieldName”: “valueMax”

}

],

“granularitySpec”: {

“type”: “uniform”,

“segmentGranularity”: “DAY”,

“queryGranularity”: “HOUR”,

“interval”: “2015-10-01/2015-11-25”

}

},

“ioConfig”: {

“type”: “index”,

“firehose”: {

“type”: “ingestSegment”,

“dataSource”: “web-firehose-minute”,

“interval”: “2015-10-01/2015-11-25”,

“filter”: {

“type”: “not”,

“field”: { “type”: “selector”, “dimension”: “_v”, “value”: 0 }

}

}

}

}

}

Any ideas would be greatly appreciated.

Do you have the full task logs?
