[jira] [Created] (HADOOP-12580) Hadoop needs a SysInfo class for
Solaris
Alan Burlison created HADOOP-12580:
--------------------------------------
Summary: Hadoop needs a SysInfo class for Solaris
Key: HADOOP-12580
URL: https://issues.apache.org/jira/browse/HADOOP-12580
Project: Hadoop Common
Issue Type: Sub-task
Components: util
Affects Versions: 2.7.1
Environment: Solaris
Reporter: Alan Burlison
Assignee: Alan Burlison
During testing multiple failures of the following sort are reported:
{code}
java.lang.UnsupportedOperationException: Could not determine OS
at org.apache.hadoop.util.SysInfo.newInstance(SysInfo.java:43)
at org.apache.hadoop.yarn.util.ResourceCalculatorPlugin.<init>(ResourceCalculatorPlugin.java:41)
at org.apache.hadoop.mapred.gridmix.DummyResourceCalculatorPlugin.<init>(DummyResourceCalculatorPlugin.java:32)
at org.apache.hadoop.mapred.gridmix.TestGridmixMemoryEmulation.testTotalHeapUsageEmulatorPlugin(TestGridmixMemoryEmulation.java:131)
{code}
This is because there is no SysInfo subclass for Solaris, from SysInfo.java
{code}
public static SysInfo newInstance() {
if (Shell.LINUX) {
return new SysInfoLinux();
}
if (Shell.WINDOWS) {
return new SysInfoWindows();
}
throw new UnsupportedOperationException("Could not determine OS");
}
{code}
An implementation of SysInfoSolaris needs to be written and plumbed in to SysInfo.
