Solutions

1. Add more or larger input files to the Gridmix input directory so the requested split sizes can be satisfied.

When it happens

Trigger: Gridmix InputStriper cannot assemble the requested number of bytes from the available input pool files, so an input split requirement cannot be satisfied.

Common situations: See trigger scenarios.
