Got the issue :
There was this new commit added to TestLocalMode in TEZ-4447 which basically
asserted
`assertEquals(VertexStatus.State.SUCCEEDED,
dagClient1.getVertexStatus(SleepProcessor.SLEEP_VERTEX_NAME,
null).getState());`
When I debugged this tests I found this :
When it tries to get from the cachedVertexStatus (size : 0) the status of
vertexName "sleep" it does not find any entry and therefore returns null. And
hence, `dagClient1.getVertexStatus(SleepProcessor.SLEEP_VERTEX_NAME, null)`
returns null and when a getState happens, it throws null pointer exception.
@abstractdog Can you please check this from your end, maybe we need to add
some config to have an entry for the Sleep vertex name in cachedVertexStatus
