Retrieve Deleted Log File from Hadoop with ElasticSearch


(Ronald Ng) #1

Dear all gens,

I am doing the product evaluation about Elasticsearch with Hadoop.

I would like to know that if I stored some log files in HDFS. when somebody deleted, by external hacker or internal stupid guy.

Any capability can retrieve it and back to the original folder?

Please advise.

This has nothing to do with Elasticsearch. If somebody deletes content from HDFS you either need to use backup or potentially some type of recycle/thrash capability (though I'm not aware of any such type of functionality).

So only trash can do it? Then how to fully utilize the feature about Hadoop append mode file system?

Since this is a HDFS specific problem, it's best to take a look at the HDFS/your Hadoop distro documentation for more information.
