Subject [jira] Commented: (HDFS-1131) each DFSClient instance uses a daemon thread for lease checking, there should be a singleton daemon for all DFSClient instances
Date Thu, 06 May 2010 19:44:48 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1131?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12864895#action_12864895

dhruba borthakur commented on HDFS-1131:
----------------------------------------

user has its own file system handle (DFSClient), this creates one daemon thread per file system
instance.
