Colin Patrick McCabe commented on HDFS-6879:
--------------------------------------------
bq. I think "host" means not computer host but organizer here. Though I think
SpanReceiverManager is clearer, I would like to keep this unchanged in order to
use the same terminology already used in HBase.
OK.
bq. That is a good point. Implementing custom sampler and hooking it will make
it. I would like to add utility for the ease of tracing to DFSClient (and
FsShell?) in follow-up JIRAs. Sampling in server-side might be a bit
difficult. It needs server-side config or sending filtering info via RPC.
I filed HDFS-6956 to discuss dynamically changing the tracing config on the
server side.
I filed HDFS-6957 to discuss allowing the client to manually specify that a
request should be traced.
This is a good start. +1
