Description

Ran into an issue where the getRawInstanceDir method on CoreDescriptor returns an invalid directory on the server. Need to track down where this bad value comes from and fix it. I suspect this has to do with me using symlinks
e.g.
I have server with solr.solr.home set to
/home/ec2-user/lucene-solr/solr/cloud87/solr, which in reality is:
/vol0/cloud87/solr as /home/ec2-user/lucene-solr/solr/cloud87 is a symlink to /vol0/cloud87
getRawInstanceDir was returning /vol0/cloud87/demo_shard1_replica1 which is missing the /solr part of the directory path, should be:
/vol0/cloud87/solr/demo_shard1_replica1
