Ted Yu created FLINK-6474:
-----------------------------
Summary: Potential loss of precision in 32 bit integer
multiplication
Key: FLINK-6474
URL: https://issues.apache.org/jira/browse/FLINK-6474
Project: Flink
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
In TaskManagerServicesConfiguration#parseNetworkEnvironmentConfiguration
{code}
if (!hasNewNetworkBufConf(configuration)) {
// map old config to new one:
networkBufMin = networkBufMax = numNetworkBuffers * pageSize;
{code}
networkBufMax is a long.
However the multiplication is done in 32 bit integer, leading to potential loss
of precision.
