我最近在Windows Server 2012 R2上将Neo4j从版本2.1.7升级到2.2.0。我一直在运行我的数据收集脚本，使用.cql文本文件中的以下cypher命令加载到数据库中：
USING PERIODIC COMMIT LOAD CSV WITH HEADERS FROM 'file:X:\\parsed\\TOI\\0031\\node_full_statuses.csv' AS line MERGE (ts:TwitterStatus {id: toInt(line.id)}) ON CREATE SET ts.id_str = line.id_str, ts.timestamp = toint(line.timestamp), ts.created_at = line.created_at, ts.favorites_count = toInt(line.favorite_count), ts.lang = line.lang, ts.source = line.source, ts.retweet_count = toInt(line.retweet_count), ts.text = line.text, ts.truncated = line.truncated ON MATCH SET ts.id_str = line.id_str, ts.timestamp = toint(line.timestamp), ts.last_updated = timestamp(), ts.created_at = line.created_at, ts.favorites_count = toInt(line.favorite_count), ts.lang = line.lang, ts.source = line.source, ts.retweet_count = toInt(line.retweet_count), ts.text = line.text, ts.truncated = line.truncated;
这在2.1.7中没有任何错误。现在当我使用相同的命令时：
PS C:\neo4j-enterprise-2.2.0\bin> .\Neo4jShell.bat -file X:\parsed\NDTV\0031\load_database.cql -v
我得到以下异常：

我觉得这很奇怪，因为我在使用merge命令之前没有从duplicates中获得任何错误（id和id_str是唯一约束）。这似乎表明它是导致回滚的PreexistingIndexEntryConflictException。
如果我再次运行命令行命令，我会得到一个不同的例外：

这是1000行提交周期开始时的事务。所有1000行都在数据库中。 （我已经单独删除它们并获得相同的异常，并且nodeID增加1）我需要删除初始错误事务所在的提交周期的1000行以使脚本继续前进。
我的问题是：有没有办法解决这个问题，以便合并正常运行，而不会在Neo4j说看起来不错的事务上获得这个奇怪的异常，但它不会提交？
我不认为我的工作非常好，并且不喜欢任何建议。
