Hello,
When I executing an export query, sometimes I get the error:
{code:java}
[c:text s:shard1 r:core_node3 x:text_shard1_replica_n1] o.a.s.c.SolrCore
java.lang.IllegalArgumentException: Unknown directory:

After that, working with the "Unknown" collection is impossible until solr
restarts. A few words about my queries - all of them consist of "fq" with
\{!join from=...} and "q" of different complexity. In my experience, the
complexity of "q" doesn't affect this error.
The exception happens only when using export, with /select handler same query
works well. Seems using export + query with join sometimes causes a bug.
