Quckstart VM Cloudera - Hadoop Solution Backup

avatar
Rising Star

Hi, 

My Virtual Machine from Cloudera in VirtualBox has already crash two times. As I am in the beginning of the project, it wasn't a very "tragic" problem. However, in future I will have some big solutions with Hadoop (HDFS, Pig, Hive and Spark) so my question is:

How to do a backup for this solution and where I can save them to not lose my work?

Many thanks!

PS: The log when the VM Crash is this:

The application had a problem and crashed.

Unfornunately, the crash reporter is unable to submit a report for this crash.

Detail: The application did not identify itself.
