Yonik Seeley commented on SOLR-1698:
------------------------------------
Looking into LBHttpSolrServer more, it looks like we have some serious concurrency issues. When a request does fail, a global lock is aquired to move from alive to zombie - but this same lock is used while making requests to check if zombies have come back (i.e. actual requests to zombies are being made with the lock held!).
For distributed search use (SearchHandler) I'm thinking of going with option #2 from my previous message (have a single static LBHttpSolrServer instance that's shared for all requests, with an extra method that allows passing of a list of addresses on a per-request basis.). I'll address the concurrency issues at the same time.

[jira] Updated: (SOLR-1698) load balanced distributed search
Posted by "Yonik Seeley (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/SOLR-1698?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yonik Seeley updated SOLR-1698:
-------------------------------
Attachment: SOLR-1698.patch
Draft patch to LBHttpSolrServer that lays the groundwork for being able to more easily use it in distributed search. This also removes much of the locking.
Next step will be to add a method that allows one to query an arbitrary server list in the given order. This will involve the zombie list, but not the "alive" list. We also need to avoid never-ending growth of the zombie list (and never-ending pinging of servers that are gone) by setting a ping limit.

------------------------------------
This is related to the solr cloud branch, but is perhaps separable enough that I thought I'd try integrating into trunk.
We could add pipe delimiters between equivalent shards - useful for testing, troubleshooting, and ad hoc requests, even when shard info will be retrieved from zookeeper.
Example shards param:
shards=localhost:8983/solr|localhost:8985/solr,localhost:7574/solr|localhost:7576/solr

Not sure what's going on... but it seems like if I have more than one load balancer instance that only one does zombie checks. Really strange - I've been banging my head against the wall for a while now.

-------------------------------------------------------------
note: it appears that hosts that don't exist (DNS failure) are loadbalanced fine on Windows, but cause the tests to fail (specifically TestDistributedSearch) on at least Ubuntu. Looking into it...
update: looks like the issue was down to the DNS provider returning a "302 Found" and an actual response for the bad host. If I add a ".com" to the bad host, everything starts working again. That's what I've done for now.

Posted by "Yonik Seeley (JIRA)" <ji...@apache.org>.

Yonik Seeley updated SOLR-1698:
-------------------------------
Attachment: SOLR-1698.patch
Latest patch, everything back to working. This fixes the load balancing algorithm to try dead servers if no live servers are available, adds tests for this case, and a bunch of other minor cleanups.
I'll merge on the cloud branch very soon and give a little time for others to review before committing to trunk.

Yonik Seeley updated SOLR-1698:
-------------------------------
Attachment: SOLR-1698.patch
Attaching new patch, still limited to LBHttpSolrServer at this point.
- includes tests
- adds a new expert-level API:
public Rsp request(Req req) throws SolrServerException, IOException
I chose objects (Rsp and Req) since I imagine we will need to continue to add new parameters and controls to both the request and the response (esp the request... things like timeout, max number of servers to query, etc). The Rsp also contains info about which server returned the response and will allow us to stick with the same server for all phases of a distributed request.
- adds the concept of "standard" servers (those provided by the constructor or addServer)... a server on the zombie list that isn't a standard server won't be added to the alive list if it wakes up, and will not be pinged forever.

Yonik Seeley edited comment on SOLR-1698 at 1/5/10 5:13 PM:
------------------------------------------------------------
Another big question is: can we use LBHttpSolrServer for this, or are the needs too different?
Some of the issues:
- need control over order (so same server will be used in a single request)
- if we have a big cluster (100 shards), we don't want every node or every core to have 100 background threads checking liveness
- one request may want to hit addresses [A,B] while another may want [A,B,C] - a single LBHttpSolrServer can't currently do both at once, and separate instances wouldn't share liveness info.
One way: have many LBHttpSolrServer instances (one per shard group) but have them share certain things like the liveness of a shard and the background cleaning threads
Another way: have a single static LBHttpSolrServer instance that's shared for all requests, with an extra method that allows passing of a list of addresses on a per-request basis.

Yonik Seeley commented on SOLR-1698:
------------------------------------
Another problem with the current load balancing algorithm is that if someone bounces both servers (or there is a temporary loss of network connectivity or whatever), they won't be marked up again until a successful ping (by default 1 minute later).
Instead, it seems like we should first try all live servers, and then try all dead servers to see if they are still truly dead before failing a request.
