callback with active state of node
Hello, We are using solr ver 4.3.1 and running them in solrcloud mode. We would like to keep some dynamic configs under data directory of every shards and/or replica of a collection. I would like to know that if nodes in not in active state (lets say it is in recovery or other stats), and if it comes back to active state, is there any callback can be registered for active state? If the component is solrcoreaware, would that component's inform method called every time, the nodes come back to active state? Thanks, Ronak

QueryElevationComponent always reads config from zookeeper
Hello,
I was looking into "QueryElevationComponent" component.
As per the spec (http://wiki.apache.org/solr/QueryElevationComponent), if
config is not found in zookeepr, it should be loaded from data directory.
However, I see the bug. It doesn't seem to be working even in latest 4.7.2
release.
I have checked the latest code and found this:
Map getElevationMap(IndexReader reader, SolrCore
core) throws Exception {
synchronized (elevationCache) {
Map map = elevationCache.get(null);
if (map != null) return map;
map = elevationCache.get(reader);
if (map == null) {
String f = initArgs.get(CONFIG_FILE);
if (f == null) {
throw new SolrException(SolrException.ErrorCode.SERVER_ERROR,
"QueryElevationComponent must specify argument: " +
CONFIG_FILE);
}
log.info("Loading QueryElevation from data dir: " + f);
Config cfg;
ZkController zkController =
core.getCoreDescriptor().getCoreContainer().getZkController();
if (zkController != null) {
cfg = new Config(core.getResourceLoader(), f, null, null);
} else {
InputStream is = VersionedFile.getLatestFile(core.getDataDir(),
f);
cfg = new Config(core.getResourceLoader(), f, new
InputSource(is), null);
}
map = loadElevationMap(cfg);
elevationCache.put(reader, map);
}
return map;
}
}
As per this code, we will never be able to load config from data directory
if zookeepr exists.
Can we fix this issue?
Thanks,
Ronak
Re: Class not found ICUFoldingFilter (SOLR-4852)
Hello Shawn,
Thanks for your reply.
Yes, I have defined ${solr.solr.home} explicitly, and all the mentioned
jars present in ${solr.solr.home}/lib. solr.log also shows that those files
are getting added once (grep "icu4" solr.log). I could see the lines in
log,
INFO - 2014-04-15 15:40:21.448; org.apache.solr.core.SolrResourceLoader;

Adding 'file:/solr/lib/lucene-analyzers-uima-4.3.1.jar' to classloader
But, still, I get the same exception ICUFoldingFilter not found. However,
coping those files to WEB-INF/lib, works fine for me.
Thanks,
Ronak

Class not found ICUFoldingFilter (SOLR-4852)
Hello, I am facing the same issue discussed at SOLR-4852. I am getting below error: Caused by: java.lang.NoClassDefFoundError: Could not initialize class org.apache.lucene.analysis.icu.ICUFoldingFilter at org.apache.lucene.analysis.icu.ICUFoldingFilterFactory.create(ICUFoldingFilterFactory.java:50) at org.apache.solr.analysis.TokenizerChain.createComponents(TokenizerChain.java:67) I am using solr-4.3.1. As discussed at SOLR-4852, I had all the jars at (SOLR_HOME)/lib and there is no reference to lib via any of solrconfig.xml or schema.xml. I have also tried with setting "sharedLib=foo", but that also didn't work. However, if I removed all the below files: icu4j-49.1.jar lucene-analyzers-morfologik-4.3.1.jar l ucene-analyzers-stempel-4.3.1.jar solr-analysis-extras-4.3.1.jar lucene-analyzers-icu-4.3.1.jar lucene-analyzers-smartcn-4.3.1.jar lucene-analyzers-uima-4.3.1.jar from $(solrhome)/lib and move to solr-webapp/webapp/WEB-INF/lib things are working fine. Any guess? Any help? Thanks, Ronak
