Examples of org.apache.lucene.index.IndexWriter.rollback()

org.apache.lucene.index.IndexWriter.rollback()
Close the IndexWriter without committing any changes that have occurred since the last commit (or since it was opened, if commit hasn't been called). This removes any temporary files that had been created, after which the state of the index will be the same as it was when commit() was last called or when this writer was first opened. This also clears a previous call to {@link #prepareCommit}. @throws IOException if there is a low-level IO error

              LOG.error(
                  "Index is corrupted, RowIds are found in wrong shard [{0}/{1}], cancelling index import for [{2}]",
                  shard, table, directory);
            }
            LOG.info("Starting rollback on [{0}/{1}]", shard, table);
            indexWriter.rollback();
            LOG.info("Finished rollback on [{0}/{1}]", shard, table);
            String name = dirPath.getName();
            int lastIndexOf = name.lastIndexOf('.');
            String badRowIdsName = name.substring(0, lastIndexOf) + ".bad_rowids";
            fileSystem.rename(dirPath, new Path(dirPath.getParent(), badRowIdsName));
