-----------------------------------
Summary: Discrepancy among numeric constants corresponding to
frequency of writing in TextAggregatorWriter
Key: GIRAPH-739
URL: https://issues.apache.org/jira/browse/GIRAPH-739
Project: Giraph
Issue Type: Bug
Reporter: Kyle Orlando
Priority: Minor
In the TextAggreggatorWriter class in org.apache.giraph.aggregators, there are
static constants at the top of the class that correspond to the frequency of
writing.
The _NEVER_ constant corresponds to never writing anything to a file, and it is
assigned an (int) value of 0.
_AT_THE_END_ corresponds to writing to a file only once, when the computation
is over, and it is assigned a numeric value of -1.
The third type of frequency is where the discrepancy exists: _ALWAYS_
corresponds to writing to a file in every superstep, and it is also assigned a
numeric value of -1.
_ALWAYS_'s value should be changed to a 1. This is because the condition for
writing (as governed by the shouldWrite() method) can be met when superstep %
frequency == 0, which is always the case when frequency == 1.
