------------------------------

             Summary: Lucene queries cannot be executed on an accessor
                 Key: GEODE-5061
                 URL: https://issues.apache.org/jira/browse/GEODE-5061
             Project: Geode
          Issue Type: Bug
          Components: lucene
            Reporter: nabarun


h2. Current:

An Apache Geode user can execute a Lucene query on an accessor without ever creating a Lucene index. This should not be allowed but it is and it causes a stack overflow when we execute a Lucene query from the accessor. This can be observed in the below test case.

 
{code:java}
public void asynchronousLuceneIndexCreationWithDifferentFieldsMustFail(
 RegionTestableType regionTestType) throws Exception {
 SerializableRunnableIF createIndex = () -> {
 LuceneService luceneService = LuceneServiceProvider.get(getCache());
 luceneService.createIndexFactory().addField("text").create(INDEX_NAME, REGION_NAME);
 };
 dataStore1.invoke(() -> initDataStore(createIndex, regionTestType));
 dataStore2.invoke(() -> initDataStore(createIndex, regionTestType));
 accessor.invoke(() -> initAccessor(createIndex, regionTestType));

 putDataInRegion(accessor);
 assertTrue(waitForFlushBeforeExecuteTextSearch(accessor, 60000));
 assertTrue(waitForFlushBeforeExecuteTextSearch(dataStore1, 60000));
 executeTextSearch(accessor);

 dataStore1.invoke(() -> destroyIndex());

 // re-index stored data
 AsyncInvocation ai1 = dataStore1.invokeAsync(() -> {
 recreateIndex();
 });
 
 dataStore2.invoke(() -> closeCache());
 ai1.join();
 aia.join();
 assertTrue(waitForFlushBeforeExecuteTextSearch(dataStore1, 60000));

 ai1.checkException();

 putAllDataIntoRegion(accessor);

 executeTextSearch(accessor);
}{code}
 

However we can see that the issue is resolved when the accessor creates the Lucene Index. 

This can be seen in the below test case.

 
{code:java}
public void asynchronousLuceneIndexCreationWithDifferentFieldsMustFail(
 RegionTestableType regionTestType) throws Exception {
 SerializableRunnableIF createIndex = () -> {
 LuceneService luceneService = LuceneServiceProvider.get(getCache());
 luceneService.createIndexFactory().addField("text").create(INDEX_NAME, REGION_NAME);
 };
 dataStore1.invoke(() -> initDataStore(createIndex, regionTestType));
 dataStore2.invoke(() -> initDataStore(createIndex, regionTestType));
 accessor.invoke(() -> initAccessor(createIndex, regionTestType));

 putDataInRegion(accessor);
 assertTrue(waitForFlushBeforeExecuteTextSearch(accessor, 60000));
 assertTrue(waitForFlushBeforeExecuteTextSearch(dataStore1, 60000));
 executeTextSearch(accessor);

 dataStore1.invoke(() -> destroyIndex());

 // re-index stored data
 AsyncInvocation ai1 = dataStore1.invokeAsync(() -> {
 recreateIndex();
 });
 AsyncInvocation aia = accessor.invokeAsync(() -> {
 recreateIndex();
 });

 dataStore2.invoke(() -> closeCache());
 ai1.join();
 aia.join();
 assertTrue(waitForFlushBeforeExecuteTextSearch(dataStore1, 60000));

 ai1.checkException();

 putAllDataIntoRegion(accessor);

 executeTextSearch(accessor);
}{code}
 

 
h2. Solution:

 

Make sure that Lucene queries cannot be executed in the accessor if the accessor has not created the Lucene index used in the query.
