Hoss Man updated SOLR-6744:
---------------------------
Description:
If trying to rename the uniqueKey field using 'fl' in a distributed query (ie:
SolrCloud config), an NPE is thrown.
The workarround is to redundently request the uniqueKey field, once with the
desired alias, and once with the original name
Example...
http://localhost:8983/solr/cloudcollection/select?q=*%3A*&wt=xml&indent=true&fl=key:id
Work around:
http://localhost:8983/solr/cloudcollection/select?q=*%3A*&wt=xml&indent=true&fl=key:id&fl=id
Error w/o work around...

Summary: fl renaming / alias of uniqueKey field generates null pointer
exception in SolrCloud configuration (was: fl renaming of uniqueKey field
generates null pointer exception in SolrCloud configuration)
i edited the summary & description a bit to fix up the formatting and point out
the workaround (as noted by Jeon Woosung on the mailing list)
the root issue is that the the distributed processing code relies on the
uniqueKey field to rectify & merge information from each shard across the
various distributed process from shards, and the NPE comes from trying to do
this lookup on the uniqueKey field name.
