ES-MongoDB学习错误1_Could not import mongo_connector.doc_managers.elastic_doc_manager

安装前面几篇文章，安装好mongo_connector后，进行文件从MongoDB到ES的备份，使用下面的命令操作：

<span style="font-size:14px;">mongo-connector -m localhost:27017 -t localhost:9200 -d elastic_doc_manager</span>

出现错误：

<span style="font-size:14px;"><pre name="code" class="html">No handlers could be found for logger "mongo_connector.util"Traceback (most recent call last):  File "/usr/local/bin/mongo-connector", line 11, in <module>    sys.exit(main())  File "/usr/local/lib/python2.7/site-packages/mongo_connector/util.py", line 85, in wrapped    func(*args, **kwargs)  File "/usr/local/lib/python2.7/site-packages/mongo_connector/connector.py", line 1041, in main    conf.parse_args()  File "/usr/local/lib/python2.7/site-packages/mongo_connector/config.py", line 118, in parse_args    option, dict((k, values.get(k)) for k in option.cli_names))  File "/usr/local/lib/python2.7/site-packages/mongo_connector/connector.py", line 824, in apply_doc_managers    module = import_dm_by_name(dm['docManager'])  File "/usr/local/lib/python2.7/site-packages/mongo_connector/connector.py", line 814, in import_dm_by_name    "vailable doc managers." % full_name)mongo_connector.errors.InvalidConfiguration: Could not import mongo_connector.doc_managers.elastic_doc_manager. </span>

<span style="font-size:14px;">It could be that this doc manager has been moved out of this project and is maintained elsewhere. </span>

<span style="font-size:14px;">Make sure that you have the doc manager installed alongside mongo-connector. Check the README for a list of available doc managers.[iienet@slave1 site-packages]$</span>

根据说明，可能是elastic_doc_manager的问题，继续深入寻找原因

mongo_connector的安装位置是

<span style="font-size:14px;">[iienet@slave1 site-packages]$ lsbson                                 pysolr-3.4.0.dist-infoeasy-install.pth                     pysolr.pyelastic_doc_manager-0.1.0.dist-info  pysolr.pycelasticsearch                        READMEelasticsearch-1.9.0.dist-info        requestsgridfs                               requests-2.9.1.dist-infomongo_connector                      setuptools-20.6.7-py2.7.eggmongo_connector-2.3.dist-info        setuptools.pthpip-8.1.1-py2.7.egg                  urllib3pymongo                              urllib3-1.15.dist-infopymongo-3.2.2-py2.7.egg-info[iienet@slave1 site-packages]$ pwd/usr/local/lib/python2.7/site-packages[iienet@slave1 site-packages]$ </span>

这是改正错误后的结果，出现错误前，里面并没有es的信息

继续查找elastic_doc_manager的相关信息

地址是

https://pypi.python.org/pypi/elastic-doc-manager#downloads

发现它需要安装

<span style="font-size:14px;">pip install elastic-doc-manager</span>

安装后，重新操作，问题解决。
