stack updated HBASE-18106:
--------------------------
Hadoop Flags: Incompatible change,Reviewed
Release Note:
Admin.listProcedures and Admin.listLocks were renamed to getProcedures and
getLocks (listProcedures was added to hbase 1.2). This change was done in an
incompatible way -- we just yanked listProcedures (Because Admin Interface is
not compatible with hbase1).
Main changes:
- ProcedureInfo and LockInfo were removed, we use JSON instead of them
- Procedure and LockedResource are their server side equivalent
- Procedure protobuf state_data became obsolate, it is only kept for
reading previously written WAL
- Procedure protobuf contains a state_message field, which stores the
internal
state messages (Any type instead of bytes)
- Procedure.serializeStateData and deserializeStateData were changed
slightly
- Procedures internal states are available on client side
- Procedures are displayed on web UI and in shell in the following jruby
format:
{ ID => '1', PARENT_ID = '-1', PARAMETERS => [ ..extra state
information.. ] }
was:
Admin.listProcedures and Admin.listLocks were renamed to getProcedures and
getLocks.
listProcedures permission has been renamed to getProcedures and getLocks
permission was introduced.
Marked as an incompat change.

> ProcedureInfo was introduced as a lowest-common-denominator POJO that could
> be used as a facade on PB Procedures. It was good for showing state of
> Procedure framework in shell and UI.
> Its a bit weird though. Its up in hbase-common rather than in Procedure and
> it can only ever show a subset of the Procedure info.
> I was thinking we could use the pb3.1 pb->JSON utility instead and emit a
> JSON String wherever we need to export a view on procedure internals.
> This issue is about exploring this possibility. Would depend on our having an
> upgraded guava (so probably depends on the 'pre-build' project).
> From ProcedureInfo and LockInfo need fixing in
