gpmfr is using 'gpddboost --ls' in the background to get a list of the backup files. The list is then parsed and one of the values is a size of the file. parseBackupListing function located in /usr/local/greenplum-db- is not able to parse a 0 size file and returns an empty object. This further crashes the gpmfr tool.

Gpmfr will fail on gp_dump_20170602081532_ao_state_file as it has a 0 size 


The current workaround is to manually remove 0 size files from the DataDomain. Use "gpddboost --ls" to identify the 0 size files.
