Description
Steps to reproduce:
- Enable graphite metrics via props file. Example:
hoodie.metrics.on=true hoodie.metrics.reporter.type=GRAPHITE hoodie.metrics.graphite.host=<host> hoodie.metrics.graphite.port=<port> hoodie.metrics.graphite.metric.prefix=<metrics_prefix>
- Run the Deltastreamer
- Note the following exception:

The important line being:
- field (class: org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamerMetrics, name: overallTimer, type: class org.apache.hudi.com.codahale.metrics.Timer)
FIX:
Make the `Timer` member variables in the `HoodieDeltaStreamerMetrics` class transient so that they are not serialized over the wire.
