Jason Wambach commented on SOLR-346:
------------------------------------

The patched line should be:

name=`perl -e 'chdir q|'${data_dir}'|; print ((sort grep 
{/^snapshot[.][1-9][0-9]{13}$/} <*>)[-1])'`

not

name=`perl -e 'chdir q|${data_dir}|; print ((sort grep 
{/^snapshot[.][1-9][0-9]{13}$/} <*>)[-1])'`

The latter will not properly evaluate the data_dir env variable.

> A directory in the Solr data directory is causing snapinstaller to fail.  
> Snapinstaller should be improved to ignore any much non-snapshot as possible.
