Subject Re: vfs classpath could not replicate
Date Wed, 26 Sep 2018 20:16:51 GMT
It looks like the error is when vfs tries to create a temporary file in
your tmpdir. I would check that your java.io.tmpdir points to a directory
that exists and has the appropriate permissions for the user running the
Accumulo process.
