-----------------------------------------
Summary: Local Flink cluster allocates too much memory
Key: FLINK-2235
URL: https://issues.apache.org/jira/browse/FLINK-2235
Project: Flink
Issue Type: Bug
Components: Local Runtime, TaskManager
Affects Versions: 0.9
Environment: Oracle JDK 1.6
Eclipse
Reporter: Maximilian Michels
Priority: Minor
When executing a Flink job locally, the task manager gets initialized with an
insane amount of memory. After a quick look in the code it seems that the call
to {{EnvironmentInformation.getSizeOfFreeHeapMemoryWithDefrag()}} returns a
wrong estimate of the heap memory size.
Moreover, the same user switched to Oracle JDK 1.8 and that made the error
disappear. So I'm guessing this is some Java 1.6 quirk.
