Gary Helmling updated HBASE-14821:
----------------------------------
Resolution: Fixed
Release Note: Configuration properties for
org.apache.hadoop.hbase.mapreduce.TableOutputFormat can now be overridden by
prefixing the property keys with "hbase.mapred.output.". When the
configuration is applied to TableOutputFormat, these entries will be rewritten
with the prefix removed -- ie.
"hbase.mapred.output.hbase.security.authentication" becomes
"hbase.security.authentication". This can be useful when directing output to a
peer cluster with different security configuration, for example.
Status: Resolved (was: Patch Available)
Thanks for reviews [~chenheng] and [~eclark]!
Committed to master, branch-1, and branch-1.2.
> CopyTable should allow overriding more config properties for peer cluster

> When using CopyTable across two separate clusters, you can specify the ZK
> quorum for the destination cluster, but not much else in configuration
> overrides. This can be a problem when the cluster configurations differ,
> such as when using security with different configurations for server
> principals.
> We should provide a general way to override configuration properties for the
> peer / destination cluster. One option would be to allow use of a prefix for
> command line properties ("peer.property."). Properties matching this prefix
> will be stripped and merged to the peer configuration.
