--------------------------------

             Summary: Summarize output when GetFlags returns InvalidArgument
                 Key: KUDU-2964
                 URL: https://issues.apache.org/jira/browse/KUDU-2964
             Project: Kudu
          Issue Type: Bug
          Components: ksck
    Affects Versions: 1.11.0
            Reporter: Adar Dembo


If running a new ksck against a cluster that doesn't support GetFlags RPC calls, the output looks something like this:
{noformat}
...
unable to get flag information for tablet server c3f2cbaee6bf495894fb94cbeb691111 (004.mydomain.local:7050): Invalid argument: Call on service kudu.server.GenericService received at 172.22.152.35:7050 from 172.22.152.225:43560 with an invalid method name: GetFlags

tserver flag check error: 93 of 93 tservers' flags were not available
{noformat}

It'd be nicer if we just summarized the unavailability (or throttled the responses) to avoid the spew.
