Attila Doroszlai created HDDS-10581:
---------------------------------------
Summary: NPE in SummarySubCommand
Key: HDDS-10581
URL: https://issues.apache.org/jira/browse/HDDS-10581
Project: Apache Ozone
Issue Type: Bug
Components: Ozone CLI
Reporter: Attila Doroszlai
Assignee: Mohammad Arafat Khan
{{TestNSSummaryAdmin}} invokes various subcommands of {{ozone admin
namespace}}. It only checks for certain patterns in the output. NPE occurs in
{{SummarySubCommand}}, but it is silently ignored. (It can be observed by
logging {{getErrContentString()}}).

Note: this changes slightly after HDDS-10540, but the problem is similar.
{code}
Cannot invoke "com.fasterxml.jackson.databind.JsonNode.asInt()" because the
return value of "com.fasterxml.jackson.databind.JsonNode.get(String)" is null
