[jira] [Updated] (REEF-1539) Fix memory leak in InteropUtil.cpp
[ https://issues.apache.org/jira/browse/REEF-1539?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Patrick Chung updated REEF-1539:
--------------------------------
Description:
{{ManagedByteArrayFromJavaByteArray}} in Org.Apache.REEF.Bridge.InteropUtil.cpp uses JNI {{GetByteArrayElements}} but does not release the bytes. This causes the driver to slowly leak memory over time, which is exacerbated if the driver message is large.
JNI documentation recommends that {{Release<PrimitiveType>ByteArrayElements}} be called after {{Get<PrimitiveTypeType>ByteArrayElements}} to avoid leaking memory, since the returned array may be a copy of the Java array.
