Better exception handling for large number of edges: GIRAPH-1203
----
> Throw better exception when edge serialisation fails because of too many edges

> Key: GIRAPH-1203
> URL: https://issues.apache.org/jira/browse/GIRAPH-1203
> Project: Giraph
> Issue Type: Improvement
> Reporter: Aanchal Dalmia
> Priority: Minor
>
> When a vertex has a large number of edges, during serialization, the edges
> would not fit into the byte array. The upper limit on the size of the array
> is the maximum integer value. When this is crossed, the size of the byte
> array becomes negative, since the integer overflows.
> Throw a better exception when this happens.
