Colin Patrick McCabe commented on HDFS-7135: -------------------------------------------- bq. This is effectively a dupe of HDFS-6956. HDFS-6956 is about servers, this is about clients. It's not possible to do an RPC to clients to change their tracing configuration because clients normally don't expose a port and a listening service to the world. Plus clients are often short-lived, so by the time you could even do an RPC, the client might have exited. bq. Adding manual tracing command which can be used like 'hdfs dfs -trace -ls /'. I sort of appreciate the simplicity of this interface, but I'm not sure how I feel about this patch. It seems more consistent to configure client-side tracing by setting a configuration key. I suppose the \-trace command added here can simply override that configuration, though. > Add trace command to FsShell > ---------------------------- > > Key: HDFS-7135 > URL: https://issues.apache.org/jira/browse/HDFS-7135 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: hdfs-client > Reporter: Masatake Iwasaki > Assignee: Masatake Iwasaki > Attachments: HDFS-7135-0.patch, HDFS-7135-1.patch > > > Adding manual tracing command which can be used like 'hdfs dfs -trace -ls /'. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
