Re: Problems starting index node

[north jetty]

btw i am using version 0.8.2

Hi north,

What version is your apache commons-collections? 

UnmodifiableMap is present only in version 3.0 and later, maybe this is a jar version or classpath issue?

Did some snooping, appears the path: "org/apache/commons/collections/map/UnmodifiableMap" has changed in version 4 (i'm using version 4-4.1) to "org/apache/commons/collections4/map/UnmodifiableMap"

What do you think?

Certainly appreciate the help,

Troy

Hey guys, what is an index node?

Do you mean an overlord? middlemanager? Are you trying to ingest data via Hadoop?
