NullPointerException thrown during updates to index
Hi,
I'm running a distributed solr index (3 nodes) and have noticed frequent
exceptions thrown during updates. The exception (see below for full trace)
occurs in the mergeIds function of QueryComponents, in this code block:
Map<Object,ShardDoc> resultIds = new HashMap<Object,ShardDoc>();
for (int i=resultSize-1; i>=0; i--) {
ShardDoc shardDoc = (ShardDoc)queue.pop();
shardDoc.positionInResponse = i;
// Need the toString() for correlation with other lists that must
// be strings (like keys in highlighting, explain, etc)
resultIds.put(shardDoc.id.toString(), shardDoc);
}
specifically, in the line:
shardDoc.positionInResponse = i;
I really have no idea why this would be happening or how to begin debugging
this error. Any ideas would be greatly appreciated.
Thanks,
-Harish

Just to clarify, the error is being thrown FROM a search, DURING an update.
This error is making distributed SOLR close to unusable for me. Any ideas?
Does SOLR fail on searches if one node takes too long to respond?

what do you mean "during updates" ? ... QueryComponent isn't used at all

I'm not very familiar with the code in question, but i opened a bug to
track it, please update with any new info you may have as you do more

I'm using a very slightly modified version of a nightly build from the middle
of September.
It seems like this isn't the only report of problems of this sort:

What version are you using? If a nightly build, from when?
Thanks
