Hi Team,


According to the Flink documentation, in the APP mode, the application jar
should be bundled with the Flink image. However, building an image for each
new application can be difficult. Can we introduce new commands that will
help to download the required jar locally before starting Flink JM or TM
containers? This should be a simple command that depends on the supported
file system (S3, HDFS, ABFS) in Flink, and the command format should be
something like this:

*./flink fs-download <Remote-FS Path> <Local-Path>*

Example:

*./flink fs-download
abfs://mycontai...@storageaccount.dfs.core.windows.net/jars /tmp/appjars
<http://mycontai...@storageaccount.dfs.core.windows.net/jars /tmp/appjars>*

I have already tested this in my cluster, and it is working fine. Before
raising a JIRA ticket, I would like to get suggestions from the community.


Thanks and Regards
Surendra
