Alex Petrov commented on CASSANDRA-12035: ----------------------------------------- I have several remarks: * {{AbstractPrinter}} class is defined abstract, although never inherited from and has no abstarct methods. * namespace has been changed, so changes are a bit harder to track I've restructured classes a bit and moved them to the original namespace. However, what I've noticed is that StatsPrinter is not very well utilised in {{Default}} implementations, for example, {{ data.convert2Map()}} is not called at all. Do you think it'd make sense to use it? You can find the updated version of the patch [here|https://github.com/ifesdjeen/cassandra/tree/12035-trunk], please let me know what you think. > Structure for tpstats output (JSON, YAML) > ----------------------------------------- > > Key: CASSANDRA-12035 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12035 > Project: Cassandra > Issue Type: Improvement > Components: Tools > Reporter: Hiroyuki Nishi > Assignee: Hiroyuki Nishi > Priority: Minor > Attachments: CASSANDRA-12035-trunk.patch, tablestats_result.json, > tablestats_result.txt, tablestats_result.yaml, tpstats_result.json, > tpstats_result.txt, tpstats_result.yaml > > > In CASSANDRA-5977, some extra output formats such as JSON and YAML were added > for nodetool tablestats. > Similarly, I would like to add the output formats in nodetool tpstats. > Also, I tried to refactor the tablestats's code about the output formats to > integrate the existing code with my code. > Please review the attached patch. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
