Subject [jira] [Commented] (CASSANDRA-10649) Improve field-checking and error reporting in cassandra.yaml
Date Fri, 06 Nov 2015 15:53:27 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14993846#comment-14993846
] 

Jim Witschey commented on CASSANDRA-10649:
------------------------------------------

[~sthakur] Sure, the yaml file was valid yaml; it just didn't have the correct fields for
a cassandra.yaml file.

We should be able to improve error reporting on this, though; I've changed the name of the
ticket to reflect that. Can C* set default values for fields not present in cassandra.yaml,
or validate expected fields are present in the file? An NPE is not very helpful in cases like
this.
