------------------------------------
Summary: NPE at NC startup after upgrade
Key: ASTERIXDB-1251
URL: https://issues.apache.org/jira/browse/ASTERIXDB-1251
Project: Apache AsterixDB
Issue Type: Bug
Reporter: Yingyi Bu
Assignee: Murtadha Hubail
I upgraded my instance to latest master but got this exception:
{noformat}
java.lang.NullPointerException
at
org.apache.asterix.metadata.bootstrap.MetadataBootstrap.enlistMetadataDataset(MetadataBootstrap.java:412)

{noformat}
It seems related to the recent global resource id changes.
But failing the instance forever seems not the right answer for that case. To
me, the bottomline is that the instance can at least start (with warnings in
the log saying which datasets are lost) though the old data could lose, so that
a user doesn't need to reinstall a new instance.
