Description

The root cause is that FSOperations#contentSummaryToJSON doesn't parse ContentSummary.erasureCodingPolicy into the json.

The expected behavior is that HttpFSFileSystem#getErasureCodingPolicy should at least return "" (empty string, for directories or symlinks), or "Replicated" (for non-EC files), "RS-6-3-1024k", etc.
