[jira] Commented: (HADOOP-4959) System metrics does not output
correctly for Redhat 5.1.
[ https://issues.apache.org/jira/browse/HADOOP-4959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12660598#action_12660598 ]
Doug MacEachern commented on HADOOP-4959:
-----------------------------------------
We recently added a FLOSS License Exception (borrowed from mysql-connector-java-5.1.6/EXCEPTIONS-CONNECTOR-J) to sigar, see:
http://svn.hyperic.org/trunk/EXCEPTIONS?revision=3884&root=Hyperic+SIGAR&view=markup
The intent is to make the license Apache-friendly so sigar can be used in projects such as Hadoop.
