[kepler-users] Updating a local dataset connected to EML2 Dataset Actor

[jing]

Hi, Mike:

I created a bug at http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5586

You may add comments and keep track on this bug.

Meanwhile, you may delete the cache directory before starting kepler 
when a new version of data file is available.  The cache directory 
locates at /your-home-dir/.kepler. Deleting cache dir will force kepler 
to load the file again.

Thanks,

Jing
