Re: Exception encountered during replication on slave....Any clues?

[William Pierce]

Hi, Noble:

When I hit the masterUrl from the slave box at
http://localhost:8080/postingsmaster/replication

I get the following xml response:

<?xml version="1.0" encoding="UTF-8" ?>
   - <response>
       - <lst name="responseHeader">
        <int name="status">0</int>
       <int name="QTime">0</int>
       </lst>
       <str name="status">OK</str>
        <str name="message">No command</str>
 </response>

And then when I look in the logs,  I see the exception that I mentioned. 
What exactly does this error mean that "replication is not available".    By 
the way, when I go to the admin url for the slave and click on replication, 
I see a screen with the master url listed (as above) and the word 
"unreachable" after it.    And, of course, the same exception shows up in 
the tomcat logs.

Thanks,

- Bill

are you able to hit the
http://localhost:8080/postingsmaster/replication using a browser from
the slave box. if you are able to hit it what do you see?

Just to make doubly sure,  per tck's suggestion,  I went in and
explicitly
added in the port in the masterurl so that it now reads:

http://localhost:8080/postingsmaster/replication

Still getting the same exception...

I am running solr 1.4, on Ubuntu karmic, using tomcat 6 and Java 1.6.

tck,

thanks for your quick response.  I am running on the default port
(8080).
If I copy that exact string given in the masterUrl and execute it in the
browser I get a response from solr:

<?xml version="1.0" encoding="UTF-8" ?>
- <response>
- <lst name="responseHeader">
 <int name="status">0</int>
 <int name="QTime">0</int>
 </lst>
 <str name="status">OK</str>
 <str name="message">No command</str>
 </response>

So the masterUrl is reachable/accessible so far as I am able to tell....

Thanks,

- Bill

Folks:

I am seeing this exception in my logs that is causing my replication
to
fail.    I start with  a clean slate (empty data directory).  I index
the
data on the postingsmaster using the dataimport handler and it
succeeds.
 When the replication slave attempts to replicate it encounters this
error.

Dec 7, 2009 9:20:00 PM org.apache.solr.handler.SnapPuller
fetchLatestIndex
SEVERE: Master at: http://localhost/postingsmaster/replication is not
available. Index fetch failed. Exception: Invalid version or the data
in
not
in 'javabin' format

Any clues as to what I should look for to debug this further?

Replication is enabled as follows:

The postingsmaster solrconfig.xml looks as follows:

<requestHandler name="/replication" class="solr.ReplicationHandler" >
  <lst name="master">
    <!--Replicate on 'optimize' it can also be  'commit' -->
    <str name="replicateAfter">commit</str>
    <!--If configuration files need to be replicated give the names
here
.
comma separated -->
    <str name="confFiles"></str>
  </lst>
 </requestHandler>

The postings slave solrconfig.xml looks as follows:

<requestHandler name="/replication" class="solr.ReplicationHandler" >
  <lst name="slave">
      <!--fully qualified url for the replication handler of
master -->
      <str
name="masterUrl">http://localhost/postingsmaster/replication
</str>
      <!--Interval in which the slave should poll master .Format is
HH:mm:ss . If this is absent slave does not poll automatically.
       But a snappull can be triggered from the admin or the http API
-->
      <str name="pollInterval">00:05:00</str>
   </lst>
 </requestHandler>


Thanks,
