---------------------------------------
Summary: CheckIndex.checkIndex throws IndexNotFoundException: no
segments* file found in RAMDirectory@
Key: LUCENE-6765
URL: https://issues.apache.org/jira/browse/LUCENE-6765
Project: Lucene - Core
Issue Type: Bug
Components: core/index
Affects Versions: 5.2.1
Environment: OS X, Lucene 5.2.1
Reporter: Vladimir Kuzmin
Priority: Minor
I am testing upgrade from Lucene 4.1 to 5.2.1 and found that behavior of
CheckIndex.checkIndex() changed. We used the following to create status for
empty dir (we use it for some reporting purpose):
CheckIndex.Status status = new CheckIndex(new RAMDirectory()).checkIndex();
At 5.2.1 it throws:
org.apache.lucene.index.IndexNotFoundException: no segments* file found in
RAMDirectory@51f090da
lockFactory=org.apache.lucene.store.SingleInstanceLockFactory@8b6023d: files: []
at org.apache.lucene.index.CheckIndex.checkIndex(CheckIndex.java:487)
at org.apache.lucene.index.CheckIndex.checkIndex(CheckIndex.java:466)
I expect that it should returns status with cantOpenSegments flag on.
https://lucene.apache.org/core/5_2_1/core/org/apache/lucene/index/CheckIndex.Status.html#cantOpenSegments
Is it expected behavior?
If this isn't expected, I am willing to provide a fix (should be minor) that I
could figure out on it how to contribute.
