Description

Steps to reproduce:

1. Create a two node cluster
2. Create a collection called "source" with 1 shard, 1 replica
3. Add 1000 docs with prefix a!
4. Add 100 docs with prefix b! and c! each
5. Create a new target collection with 1 shard, 1 replica and ensure that it is created on a different node than "source"
6. Issue a migrate API call with an async parameter:

   http://localhost:8983/solr/admin/collections?action=migrate&split.key=a!&collection=gettingstarted&target.collection=target&wt=json&async=acid
   

The above fails with:

ERROR - 2015-03-23 22:50:11.349; org.apache.solr.common.SolrException; Collection: gettingstarted operation: migrate failed:org.apache.solr.common.SolrException: Invalid status request: notfoundretried 6times
