zengjie created SOLR-8340:
-----------------------------
Summary: HighlightComponent throws a NullPointerException when the
attribute of ResponseBuilder which named 'onePassDistributedQuery' is 'true'
and 'rows' is greater than zero
Key: SOLR-8340
URL: https://issues.apache.org/jira/browse/SOLR-8340
Project: Solr
Issue Type: Bug
Components: highlighter
Affects Versions: 5.3.1
Reporter: zengjie
Priority: Critical
When the attribute 'onePassDistributedQuery' is 'true',QueryCompoent will not
send a ShardRequest to retrive field values, highlight values has been return
by shards in createMainQuery together.
See code below:
private void handleRegularResponses(ResponseBuilder rb, ShardRequest sreq) {
if ((sreq.purpose & ShardRequest.PURPOSE_GET_TOP_IDS) != 0) {
//merge all id and score,and ResponseBuilder.resultIds just stored id between
start to rows
mergeIds(rb, sreq);
}
if ((sreq.purpose & ShardRequest.PURPOSE_GET_TERM_STATS) != 0) {
updateStats(rb, sreq);
}
if ((sreq.purpose & ShardRequest.PURPOSE_GET_FIELDS) != 0) {
//where ResponseBuilder.onePassDistributedQuery is true,highlight values was
retrived at same time,but not truncated by 'start' and 'rows',just return top
N(N=start+rows),
returnFields(rb, sreq);
}
}
