这样访问： http://localhost:8084/solr/collection1/suggest?q=*%3A*&rows=1&wt=json&indent=true&spellcheck=true&spellcheck.q=积木&distrib=false . 可以正常suggest ,但是我 去掉 distrib 属性就报错。 

我调试 代码 ：发现问题出在：solr-core 包中的这个类 spellcheckComponent，这段代码

protected SolrSpellChecker getSpellChecker(SolrParams params) {
String[] dictName = getDictionaryNames(params);
if (dictName.length == 1) {
return spellCheckers.get(dictName[0]);
} else {
String singleStr = getDictionaryNameAsSingleString(dictName);
SolrSpellChecker ssc = spellCheckers.get(singleStr);
if (ssc == null) {
ConjunctionSolrSpellChecker cssc = new ConjunctionSolrSpellChecker();
for (String dn : dictName) {
cssc.addChecker(spellCheckers.get(dn));
}
ssc = cssc;
}
return ssc;
}
}

调试结果  dictName="pyNotokenSuggest"  （是我自定义的 suggest)

分片查询的话: return spellCheckers.get(dictName[0]);//spellCheckers是包含我定义的suggest 的。

但是 直接使用zookeeper 查询所有的话,如访问104，执行到这个句话时 spellCheckers是包含我定义的suggest的，接着它会访问103的solr,仍然会执行这段代码，但是这是会发现 spellCheckers中已经不包含我定义的 suggest,导致 空指针 异常 。。

求大神 赐教 解决办法 。！！！！！！！！！！
