Subject [jira] [Updated] (HDFS-9935) Remove LEASE_{SOFTLIMIT,HARDLIMIT}_PERIOD constants from HdfsServerConstants
Date Thu, 10 Mar 2016 03:16:40 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9935?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lin Yiqun updated HDFS-9935:
----------------------------
    Description: In HDFS-9134, it has moved the {{LEASE_SOFTLIMIT_PERIOD}},{{LEASE_HARDLIMIT_PERIOD}}
constants from {{HdfsServerConstants}} to {{HdfsConstants}} because these two constants are
used by {{DFSClient}} which is moved to {{hadoop-hdfs-client}}. And constants in {{HdfsConstants}}
can be both used by client and server side. In addition, I have checked that these two constants
in {{HdfsServerConstants}} has already not been used in project now and were all replaced
by {{HdfsConstants.LEASE_SOFTLIMIT_PERIOD}},{{HdfsConstants.LEASE_HARDLIMIT_PERIOD}}. So I
think we can remove these unused constant values in {{HdfsServerConstants}} completely. Instead
of we can use them in {{HdfsConstants}} if we want to use them in the future.  (was: In HDFS-9134,
it has moved the LEASE_{SOFTLIMIT,HARDLIMIT}_PERIOD constants from {{HdfsServerConstants}}
to {{HdfsConstants}} because these two constants are used by {{DFSClient}} which is moved
to {{hadoop-hdfs-client}}. And constants in {{HdfsConstants}} can be both used by client and
