Summary: Ensure non-metric values are returned as is for flow run
table from the coprocessor
Key: YARN-5014
URL: https://issues.apache.org/jira/browse/YARN-5014
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Vrushali C

Presently the FlowScanner class presumes existence of NumericValueConverter in
it's emitCells function. This causes an exception when we try to retrieve
non-numeric values from this table.
Exception is seen as:
