I have a data flow which uses the MR Morphline JAR. The index creation seems to work fine (the MR job itself reports success), but uploading the new indices (the go_live option) throws an Exception. In the Solr logs, I get the following messages:
|15:26:09||ERROR||CoreAdminHandler||ERROR executing merge:|
|15:26:09||ERROR||SolrCore||org.apache.lucene.index.IndexFormatTooNewException: Format version is not supported (resource: _2.nv...|
|15:26:09||ERROR||SolrDispatchFilter||null:org.apache.lucene.index.IndexFormatTooNewException: Format version is not supported (resource: ...|
I've looked about a bit, but I can't seem to find any indication of what might cause this. Is it a problem with my collection configuration?
Just to follow-up, this was my bad: the client had solr-mapreduce from the release yum repo (version 1.0), while the cluster was still on the beta (0.9.3). Once I downgraded my client the merge worked fine.
