Hoss Man created SOLR-4754:
------------------------------
Summary: solrcloud does not detect an implicit "host" and does not
provide clear error using 4x example
Key: SOLR-4754
URL: https://issues.apache.org/jira/browse/SOLR-4754
Project: Solr
Issue Type: Bug
Reporter: Hoss Man
Testing out the 4.3.0 RC3, I tried to run through the SolrCloud examples.
Following the steps for "Example A: Simple two shard cluster" my two nodes
started up w/o any obvious problem, however the I noticed the cluster graph was
empty, and attempts to index documents failed with invalid url errors when
trying to forward the distributed updates. Closer inspection of the cluster
state lead me to discover that the URLs for the nodes as registered with ZK did
not include any host information at all. (details to follow in comment)
Apparently, the logic for implicitly detecting a hostname to use with SolrCloud
failed to work, and did not cause any sort of startup error.
Important things to note:
# java clearly _did_ know what the current configured hostname was for my
machine, because it appeared correctly in the {{<title/>}} tag of the admin UI
(pulled from "/admin/system") so i don't think this probablem is specific to
any sort of glitch in my hostname configuration.
# explicitly setting the "host" sys prop (as used in the example solr.xml)
worked around the problem
# I could _not_ reproduce this problem with Solr 4.2.1 (using the 4.2.1 example
configs)
We should try to make the hostname/url detection logic smarter (i'm not sure
why it isn't working as well as the SystemInfoHandler) and it should fail
loudly on startup as last resort rather then registering the node with ZK using
an invalid URL.
