-----------------------------------------
Summary: SolrCore.bufferUpdatesIfConstructing fails on PULL
replicas
Key: SOLR-17231
URL: https://issues.apache.org/jira/browse/SOLR-17231
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Chris M. Hostetter
If a "Slice" is in the {{CONSTRUCTION}} state, then SolrCore initialization for
replicas of that Slice try to setup update buffering of the {{UpdateLog}} – but
this makes no sense for {{PULL}} replicas which have no update logs, and causes
a NPE....
{code:java}
private void bufferUpdatesIfConstructing(CoreDescriptor coreDescriptor) {
...
if (slice.getState() == Slice.State.CONSTRUCTION) {
// set update log to buffer before publishing the core
getUpdateHandler().getUpdateLog().bufferUpdates();
}
}
{code}
I believe the fix is just for {{bufferUpdatesIfConstructing}} to check the
replica type? (or do a null check on {{getUpdateLog()}} ?)
