mongoimport 2.6与2.4 [英] mongoimport 2.6 vs 2.4

问题描述

我正在从一个数据库导出数据，并将数据导入另一个数据库.当我将数据导出到具有mongo 2.6的计算机上时，但是当我将数据导入到使用mongo 2.4的VM上时.两个mongod实例都运行2.4.

I am exporting data from one database and importing data to another database. When I export the data its on a machine with mongo 2.6 but when I import the data its on a VM using mongo 2.4. Both mongod instances are running 2.4.

我不断收到此错误:

Wed Jun  4 13:13:32.604 check 0 0

导出的日期格式类似于

{ "date" : { "$date" : "2014-06-02T06:39:28.869-0700" }

我已经验证了在与mongoexport相同的机器上使用mongoimport可以正常工作，因此我认为mongoimport/export从2.4到2.6之间存在兼容性问题.由于防火墙的限制，我需要使用两台不同的计算机来移动数据.

I have verified that using mongoimport on the same machine as the mongoexport works fine, so I assume there is a compatablility issue between mongoimport/export from 2.4 to 2.6. Due to firewall restrictions I need to use the two different machines for moving the data around.

有人可以解决此问题吗?据我所知，我还没有看到以旧格式导出的选项.我也无法从发行说明中得知是什么导致了兼容性错误.

Does anybody have any good work arounds for this problem. I have not seen an option to export in the old format as far as I can tell. I also cannot tell from the release notes, what is causing the compatability error.

推荐答案

我最终使用mongodump和mongorestore代替了mongoimport和mongo导出.使用bson文档而不是json时没有兼容性问题.

I ended up using mongodump and mongorestore instead of mongoimport and mongo export. There was no compatability issue using bson documents instead of json.
