Currently we will fix this bug in an easier way and will optimize it later in
CARBONDATA-2652
> explain query shows negative skipped blocklets for bloomfilter datamap

> Key: CARBONDATA-2650
> URL: https://issues.apache.org/jira/browse/CARBONDATA-2650
> Project: CarbonData
> Issue Type: Sub-task
> Reporter: xuchuanyin
> Assignee: xuchuanyin
> Priority: Major
>
> Currently in carbondata, blocklets are pruned by default blocklet datamap
> first and then will be pruned by other index datamap later.
> In the second step, the pruning is segment scope, it will not use the pruning
> output of the default blocklet datamap, so the result number of blocklets may
> be bigger than before, thus causing negative number in skipped blocklets.
