stack commented on HBASE-18106:
-------------------------------
(Copied from HBASE-18240 where we add protobuf-util which can JSON-ify pb)
The JsonFormatter in protobuf-util is basic but should do the job. Here is
output:
kalashnikov:hbase.git stack$ ./bin/hbase
org.apache.hadoop.hbase.procedure2.TestProcedureUtil
{ "className":
"org.apache.hadoop.hbase.procedure2.ProcedureTestingUtility$TestProcedure",
"procId": "10", "submittedTime": "1498339510660", "state": "RUNNABLE",
"lastUpdate": "1498339510660", "stateData": "AA==" }
adding this main on TestProcedureUtil:
public static void main(final String [] args) throws Exception
{ final TestProcedure proc1 = new TestProcedure(10); final
ProcedureProtos.Procedure proto1 =
ProcedureUtil.convertToProtoProcedure(proc1); JsonFormat.Printer printer =
JsonFormat.printer().omittingInsignificantWhitespace();
System.out.println(printer.print(proto1)); }
For display in UI, could style the JSON and filter out state data.
For shell, could do simple one-lining (and purge state data... since it opaque.
Later we might add Stringification..)

> Fix For: 2.0.0

>
> 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
