Aaron T. Myers commented on HDFS-6334: -------------------------------------- Patch looks great to me, Kihwal. Thanks for doing it. Two little nits: # bq. + * used, a special token handling mat be needed to make sure a token acquired s/mat/may/g # The method comment for {{ConfiguredFailoverProxyProvider#useLogicalURI}} says "Logical URI is not used for IP failover." While strictly true, I'm guessing you meant to put a different comment here. +1 once these are addressed. > Client failover proxy provider for IP failover based NN HA > ---------------------------------------------------------- > > Key: HDFS-6334 > URL: https://issues.apache.org/jira/browse/HDFS-6334 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Kihwal Lee > Assignee: Kihwal Lee > Attachments: HDFS-6334.patch, HDFS-6334.v2.patch > > > With RPCv9 and improvements in the SPNEGO auth handling, it is possible to > set up a pair of HA namenodes utilizing IP failover as client-request fencing > mechanism. > This jira will make it possible for HA to be configured without requiring use > of logical URI and provide a simple IP failover proxy provider. The change > will allow any old implementation of {{FailoverProxyProvider}} to continue to > work. -- This message was sent by Atlassian JIRA (v6.2#6252)
