Subject [jira] Commented: (HADOOP-5859) FindBugs : fix "wait() or sleep() with locks held" warnings in hdfs
Date Mon, 25 May 2009 04:41:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5859?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712631#action_12712631
] 

dhruba borthakur commented on HADOOP-5859:
------------------------------------------

> 2) dataQueue lock and ackQueue lock are merged into one

Is this done to make the code simpler? Or was there some race condition that this fixes?
