----------------------------------
Summary: NPE when create a core with both explicite shard and
coreNodeName
Key: SOLR-5580
URL: https://issues.apache.org/jira/browse/SOLR-5580
Project: Solr
Issue Type: Bug
Affects Versions: 4.6
Environment: OS:Red Hat Enterprise Linux Server release 6.4 (Santiago)
Software:solr 4.6,
jdk:OpenJDK Runtime Environment (rhel-2.3.4.1.el6_3-x86_64)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)
Reporter: YouPeng Yang
In class org.apache.solr.cloud.Overseer the Line 360:
---------------------------------------------------------------------
if (sliceName !=null && collectionExists &&
!"true".equals(state.getCollection(collection).getStr("autoCreated"))) {
Slice slice = state.getSlice(collection, sliceName);
if (slice.getReplica(coreNodeName) == null) {
log.info("core_deleted . Just return");
return state;
}
}
---------------------------------------------------------------------
the slice needs to be checked null .because when create a new core with both
explicite shard and coreNodeName, the state.getSlice(collection, sliceName)
may return a null.So it needs to be checked ,or there will be an
NullpointException
---------------------------------------------------------------------
if (sliceName !=null && collectionExists &&
!"true".equals(state.getCollection(collection).getStr("autoCreated"))) {
Slice slice = state.getSlice(collection, sliceName);
if (slice != null && slice.getReplica(coreNodeName) == null) {
log.info("core_deleted . Just return");
return state;
}
}
