Noticed the INPUT_RECORDS look incorrect for the reducers that are responsible for aggregating the min/max/bloomfilter (Reducers 12, 14, 2, 6). For example Reducer 2 shows 12M input records. However looking at the task logs for Reducer 2, there were only 167 input records. > It looks like Map 1 has 2 different output vertices (Reducer 2 and Reducer 8), but the total output rows for Map 1 (rather than just the rows going to each specific vertex) is being counted in the input rows for both Reducer 2 and Reducer 8. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
