[jira] [Created] (HDFS-2934) HA: Allow configs to be scoped to all
NNs in the nameservice
HA: Allow configs to be scoped to all NNs in the nameservice
------------------------------------------------------------
Key: HDFS-2934
URL: https://issues.apache.org/jira/browse/HDFS-2934
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha, name-node
Affects Versions: HA branch (HDFS-1623)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Minor
Currently, for namenode-specific keys in HA, one must configure them as keyfoo.nameserviceid.namenodeid. However, in many cases all of the NNs in a nameservice would share the same value. So we should allow the configuration of "keyfoo.nameserviceid" to apply to all NNs. The resolution path for these keys would then be:
keyfoo.nameserviceid.nnid
keyfoo.nameserviceid (if above not set)
keyfoo (if neither of above set)
