--------------------------------------
Summary: Unexpected Histogram accumulator behavior
Key: FLINK-1096
URL: https://issues.apache.org/jira/browse/FLINK-1096
Project: Flink
Issue Type: Bug
Reporter: Sebastian Kruse
Assignee: Sebastian Kruse
Priority: Trivial
The {{Histogram}} accumulator uses the given value as both key and value for
the histogram map. Hence, the histogram always contains entries like {{key -> n
* key}} where {{n}} is the number of times that {{key}} has been added to the
histogram.
Supposedly, adding {{key}} into the histogram {{n}} times should create the
entr {{key -> n}} instead.
