CorruptIndexException on indexing after a failure occurs after segments file creation but before
any bytes are written
----------------------------------------------------------------------------------------------------------------------

                 Key: LUCENE-3627
                 URL: https://issues.apache.org/jira/browse/LUCENE-3627
             Project: Lucene - Java
          Issue Type: Bug
         Environment: Mac OS X 10.6.5, running tests in Eclipse Build id: 20100218-1602, 
java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode)

            Reporter: Ken McCracken
            Priority: Critical


FSDirectory.createOutput(..) uses a RandomAccessFile to do its work.  On my system the default
FSDirectory.open(..) creates an NIOFSDirectory.  If createOutput is called on a segments_*
file and a crash occurs between RandomAccessFile creation (file system shows a segments_*
file exists but has zero bytes) but before any bytes are written to the file, subsequent IndexWriters
cannot proceed.  The difficulty is that it does not know how to clear the empty segments_*
file.  None of the file deletions will happen on such a segment file because the opening bytes
cannot not be read to determine format and version.

I will attempt to attach a Test file demonstrates the issue; place it in your 
src/test/org/apache/lucene/store/
directory and run the unit tests with JUnit4.
