James Ji updated SOLR-3997:
---------------------------
Description:
We are currently working on having Solr files read from HDFS. We have a class
which extends Directory class to handle all file access. However, we found that
QueryElevationComponent is not using Directory class but using the native File
object.
QueryElevationComponent.inform(){
....
File fC = new File(core.getResourceLoader().getConfigDir(), f);
File fD = new File(core.getDataDir(), f);
if (fC.exists() == fD.exists()) {
throw new SolrException(SolrException.ErrorCode.SERVER_ERROR,
"QueryElevationComponent missing config file: '" + f + "\n"
+ "either: " + fC.getAbsolutePath() + " or " +
fD.getAbsolutePath() + " must exist, but not both.");
}
if (fC.exists()) {
exists = true;
log.info("Loading QueryElevation from: "+fC.getAbsolutePath());
Config cfg = new Config(core.getResourceLoader(), f);
elevationCache.put(null, loadElevationMap(cfg));
}
....
}
was:
We are currently working on having Solr files read from HDFS. We extended some
of the classes so as to avoid modifying the original Solr code and make it
compatible with the future release. So here comes the question, I found in
QueryElevationComponent, there is a piece of code checking whether elevate.xml
exists at local file system. I am wondering if there is a way to by pass this?
QueryElevationComponent.inform(){
....
File fC = new File(core.getResourceLoader().getConfigDir(), f);
File fD = new File(core.getDataDir(), f);
if (fC.exists() == fD.exists()) {
throw new SolrException(SolrException.ErrorCode.SERVER_ERROR,
"QueryElevationComponent missing config file: '" + f + "\n"
+ "either: " + fC.getAbsolutePath() + " or " +
fD.getAbsolutePath() + " must exist, but not both.");
}
if (fC.exists()) {
exists = true;
log.info("Loading QueryElevation from: "+fC.getAbsolutePath());
Config cfg = new Config(core.getResourceLoader(), f);
elevationCache.put(null, loadElevationMap(cfg));
}
....
}
Issue Type: Bug (was: Wish)
Summary: QueryElevationComponent using native File object to access
