Hi Eddie, thanks for reporting. This is a common issue with "xargs". When xargs doesn't receive any input through the pipe (i.e. if "find" doesn't find anything), it isn't smart enough to exit-early and still tries to run the "chmod" command without a filename. The "-r" flag is present in most versions of xargs to prevent this behavior. I'll create a JIRA to suggest this change. (For context: https://stackoverflow.com/questions/36617999/error-rm-missing-operand-when-using-along-with-find-command)
Also concerning though is that "find" isn't outputting any files in the first place. I'll also take a look at that. Can you provide any information on what environment you're seeing this on (OS, version, Solr version, etc.)?
