> Noticed when doing work for SOLR-15702.
> The Solr backup commands call {{BackupRepository.createDirectory}} at various
> times, while also checking that the same directory exists (via
> {{pathExists}}) at different times. The issue here is that during the
> distributed Backup commands, (sent to different nodes for each shard), one
> node might be at the part of the backup where it is calling
> {{createDirectory}} when another node is calling {{pathExists}} for the same
> directory.
> When following the BackupRepository API Spec correctly, this should not be an
> issue because {{createDirectory}} should be a no-op when the directory
> already exists. However {{GCSRepository}} does not make this check before
> creating the directory. This should be an easy fix.
