Greg Senia commented on TEZ-3105:
---------------------------------
[~gopalv] or [~hitesh] I attempted the above and Tez no longer works correctly
when testing with the above changes... I wish there was a better answer..
Looking at what the Flink folks did they did the following:
https://github.com/apache/flink/blob/6b01a89020f2de3f7710cf72336291b1e8ca8562/flink-runtime/src/main/java/org/apache/flink/runtime/util/EnvironmentInformation.java
public static long getMaxJvmHeapMemory() {
long maxMemory = Runtime.getRuntime().maxMemory();
if (maxMemory == Long.MAX_VALUE) {
// amount of free memory unknown
try {
// workaround for Oracle JDK
OperatingSystemMXBean operatingSystemMXBean =
ManagementFactory.getOperatingSystemMXBean();
Class<?> clazz =
Class.forName("com.sun.management.OperatingSystemMXBean");
Method method =
clazz.getMethod("getTotalPhysicalMemorySize");
maxMemory = (Long)
method.invoke(operatingSystemMXBean) / 4;
}
catch (Throwable e) {
throw new RuntimeException("Could not determine
the amount of free memory.\n" +
"Please set the maximum memory
for the JVM, e.g. -Xmx512M for 512 megabytes.");
}
}
return maxMemory;
}
> Tez does not run on IBM JDK 7 or 8
