I am using tranquility to push data to druid. I was trying to create these aggregates:
new DoubleSumAggregatorFactory(“publisherPrice”, “publisherPrice”),
new ApproximateHistogramAggregatorFactory(“publisherPriceHistogram”, “publisherPrice”, HISTOGRAM_RESOLUTION, HISTOGRAM_OUTPUT_BUCKETS, 0F, Float.POSITIVE_INFINITY),
and the tranq app is throwing a tons of errors:
java.lang.IllegalStateException: Failed to save new beam for identifier[druid:prod:overlord/ssp-auction-6] timestamp[2015-03-20T13:00:00.000Z]
Caused by: com.metamx.common.parsers.ParseException: Duplicate column entries found : [publisherprice]
It seems that I cannot have two aggregators for a single dimension. But it worked in previous version (I have tranq 4.0 now). Is it possible to make it work?
