Subject [jira] [Updated] (HDFS-10441) libhdfs++: HA namenode support
Date Mon, 27 Jun 2016 18:04:52 GMT

     [ https://issues.apache.org/jira/browse/HDFS-10441?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

James Clampffer updated HDFS-10441:
-----------------------------------
    Attachment: HDFS-10441.HDFS-8707.007.patch

Some minor improvements:
-HANamenode tracker now a class, added accessors so no more direct access to bool flags
-More comments
-NamenodeOperations::Connect now takes resolved endpoints vector by value(RpcEngine does as
well).  It can get called in asynchronous contexts so it's worth the small, and rare, copy
overhead to a avoid dangling ref/pointer issues.
