How to move Ignite cached data from one cluster to other cluster ?
You need to copy your persistence files. By default, they're stored in the working directory - ${IGNITE_HOME}/work. Copy that directory from the nodes of the first cluster to the nodes of the second.
Note that you need to have the same number of nodes and the same configuration for this to work.

I upgraded node from v8.x to v10.x a couple of weeks ago.
My bash history does not have timestamp enabled so I cannot tell on which date I upgraded.
Is it possible to look at any log files to get this info?
You should have rsyslog and auditd setup if you need this level of accounting. Look at the time stamps on the files, and you may see a date that matches when you installed the package. Or look to see if their is a cache directory for the tool you used to update it with etc..

I'm running storm and trident-storm local cluster. My goal is to compare them. I'd like to do it by comparing execution time. How can I see working time of every bolt in storm and in trident-storm?
The Storm UI that runs on the nimbus server can show you this. If you don't already have that running, checkout these instructions for details on how to run it (should be at the bottom of the page).
If you're trying to do this test in local mode, though, and don't have the UI, I'd recommend you not even bother. Local mode is not really representative of what kind of performance you'll see on a cluster once all your workers have started and are processing tuples.

I foolishly ran the following code
file.remove(list.files())
Is there any way of retrieving the deleted files. I am working in windows XP + R 2.15.0
You need to get a NTFS (or FAT32, though unlikely) file recovery software. Restoration and Undelete Plus are a few of them
