OperationMetrics
to ProcedureMetrics
.
NOTE: Procedure framework in hbase-procedure module accesses metrics common to most procedures
through ProcedureMetrics
interface. Metrics source classes in hbase-hadoop-compat
module provides similar interface OperationMetrics
that contains metrics common to most
operations. As both hbase-procedure and hbase-hadoop-compat are lower level modules used by
hbase-server (this) module and there is no dependency between them, this method does the
required conversion.public void incrementSnapshotObserverTime(long executionTime)
