Karl Wright commented on CONNECTORS-288:
----------------------------------------
So when I added a System.out.println of the URL in ElasticSearchAction, I no
longer get any errors; the check() response is "OK". (That is wrong, by the
way; it should return super.check() instead, which is "Connection working".)
The instrumented URL output looks like this:
[junit] URL is 'http://localhost:9200/index/_optimize'
[junit] URL is 'http://localhost:9200/index/_status'
[junit] URL is 'http://localhost:9200/index/_optimize'
[junit] URL is 'http://localhost:9200/index/_optimize'
[junit] URL is 'http://localhost:9200/index/_optimize'
... followed by the 120000 ms timeout.
Some conclusions: (1) We should fix the check() method; (2) The fact that
check() succeeds sometimes and fails others is quite disconcerting; clearly the
connector is doing something pretty wrong.
I also looked more deeply at the code itself. The addOrReplaceDocument()
method uses a synchronizer to permit only one thread to index at a time. This
does not seem correct to me, and it is thus probable that the problem stems
from improper understanding of the ManifoldCF threading model. Each connector
instance should be working with its own ElasticSearchIndex object and its own
HttpClient method so that all of the threads can operate independently without
collision.
