Subject [jira] [Updated] (HADOOP-13466) Using a separate lock class to replace using class object lock
Date Wed, 03 Aug 2016 21:33:20 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13466?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chen Liang updated HADOOP-13466:
--------------------------------
    Description: Add a separate lock class object into util, such that we can replace using
class object lock. This would make it easier for us to understand locking behaviors. e.g.,
we may easily instrument the new lock class for better understanding of locking overhead.
