HDF 3.4

figured out the issue, related to jira https://issues.apache.org/jira/browse/NIFI-6999

 

flow.xml.gz is 963 mb, where toolkit mem isn't enough to restart from ambari GUI. hence started through CLI

 

restarted the nifi from CLI rather than AMBARI , came up 

 

flow.xml.gz file size is 963MB

instance : 120GB memory

NIFI allocated mem: 45GB

toolkit  15GB mem

error: from ambari agent logs
