Description

TestNSSummaryAdmin invokes various subcommands of ozone admin namespace. It only checks for certain patterns in the output. NPE occurs in SummarySubCommand & DiskUsageSubCommand, but it is silently ignored. (It can be observed by logging getErrContentString()).

Note: this changes slightly after HDDS-10540, but the problem is similar.

Cannot invoke "com.fasterxml.jackson.databind.JsonNode.asInt()" because the return value of "com.fasterxml.jackson.databind.JsonNode.get(String)" is null
