Description

I ran into an issue with SSTableReaderTest#testOpeningSSTable test failure on macOS. The reason for failure seems that on macOS, the file modification timestamps are at a second granularity (See: https://stackoverflow.com/questions/18403588/how-to-return-millisecond-information-for-file-access-on-mac-os-x-in-java and https://developer.apple.com/legacy/library/technotes/tn/tn1150.html#HFSPlusDates). The fix is simple - bumping up the sleep time to 1 second instead of 10ms.
