[jira] [Created] (YARN-2944) SCMStore/InMemorySCMStore is not
currently compatible with ReflectionUtils#newInstance
Chris Trezzo created YARN-2944:
----------------------------------
Summary: SCMStore/InMemorySCMStore is not currently compatible with ReflectionUtils#newInstance
Key: YARN-2944
URL: https://issues.apache.org/jira/browse/YARN-2944
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Chris Trezzo
Assignee: Chris Trezzo
Priority: Minor
Currently the Shared Cache Manager uses ReflectionUtils#newInstance to create the SCMStore service. Unfortunately the SCMStore class does not have a 0-argument constructor.
On startup, the SCM fails with the following:

This JIRA is to add a 0-argument constructor to SCMStore.
