------------------------------
> CM uri encoding
> ---------------
>
> Key: HIVE-16859
> URL: https://issues.apache.org/jira/browse/HIVE-16859
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 3.0.0
> Reporter: anishek
> Assignee: anishek
>
> Currently for hive replication, the cm root uri is configured via
> "hive.repl.cmrootdir". This configuration needs to have the same value on
> both the primary and replica hive warehouse.
> CM uri should be encoded such that the cm root of the source should be part
> of the URI itself. so the cmfs uri's should be following
> {code
> }cmfs:hdfs://[authority]/[actual_location]#[checksum_of_file]_[encoded_cm_root_on_primary]
> {code}
> so that we can detect what is the root location of the source cm root at any
> target replica warehouse. Since the filesystem configurations can be
> different for the primary and replica warehouse there might be additional
> configurations will be required to create {{FileSystem}} objects to talk to
> respective filesystems. if we want to support that we can add an additional
> configuration stating the primary cm root location on the replica warehouse
> along with other fs related configurations and in that case this bug might be
> irrelevant.
