Colin Patrick McCabe commented on HDFS-7189:


bq. But I think the spans \[for queryDatanodeForHdfsBlocksMetadata comments\] 
should be in the same trace tree and as a child span instead of start a new 
trace. So we should pass the trace info (trace id parent span id) to continue 
span.

Good idea.  That way, if a {{DFSClient#getBlockStorageLocations}} call takes a 
long time, the trace might be helpful to show which datanode is lagging.

bq. Some DFSClient operations don't have trace spans, should we add them?

The operations that I didn't add tracing for broke down into two categories:
* Things that we're going to do later in the "add tracing to DFSOutputStream" 
change (this is why callAppend isn't traced, append, connectToDN, etc.)
* Things that look like they're not very time-consuming.  Like 
getCryptoProtocolVersion which just fetches the version out of a 
FileEncryptionInfo object.

Actually, though, I do see one or two things where I should add tracing, like 
getStoragePolicies.  Let me add those.

We can always add tracing to stuff later, so I don't think this should be a 
blocker for this going in.  And we will certainly adjust the trace points later 
based on what we learn... to put more in some places and fewer in others.  But 
thanks for getting me thinking about this.

bq. Typo? It should be "dst"

Argh.  Thanks

bq. In getSrcDstTraceScope, we'd better check dst != null too.

yeah

Yi Liu commented on HDFS-7189:

Thanks Colin for the patch. Overall looks very good, only following comments:

*1).* Besides {{DFSClient}}, I see the patch passes the {{traceSampler}} to 
some other classes, for example _BlockStorageLocationUtil.java_. The reason is 
{{queryDatanodesForHdfsBlocksMetadata}} is invoked by 
{{DFSClient#getBlockStorageLocations}}, but it uses a thread pool to call 
{{VolumeBlockLocationCallable}}, so it's in different thread context. If we 
don't pass {{traceSampler}}, then we will get {{NullScope}} for {{startSpan}}. 
But I think the span should be in the same trace tree and as a child span 
instead of start a new trace. So I think we should pass the trace info (trace 
id parent span id) to continue span.

For {{CacheDirectiveIterator}}, {{CachePoolIterator}} and 
{{EncryptionZoneIterato}}, it indeed can be used by user in new places of 
different threads, so it's OK we pass {{traceSampler}} and can start new trace 
if it's indeed in different thread.

*2).*
Some DFSClient operations don't have trace spans, should we add them?

*3).*
{code}
private static final byte[] DST = "src".getBytes(Charset.forName("UTF-8"));
{code}
Typo? It should be {{"dst"}}

*4).*
In {{getSrcDstTraceScope}}, we should also check {{dst != null}}

Colin Patrick McCabe commented on HDFS-7189:


bq. \[is adding unwrapRemoteException to getStoragePolicies\] a bug fix?

Hmm.  Good question.  I looked into this a little more, and I think I will skip 
adding new invocations of {{unwrapRemoteException}} in this patch.  The 
unwrapping is only needed when the NameNode actually throws one of those 
exceptions, but I don't think that can happen for {{getStoragePolicies}} or 
many of the other functions here.  Plus, adding that stuff muddies the 
waters... it would be better to do it in a separate patch than to combine it 
with this one.

bq. Removing checkOpen(); in delete is intentional ?

Ah, but the one-argument version of {{delete}} now calls another override of 
the function, which then calls {{checkOpen}}.  So it should be OK.

bq. Is this intentional... calling trace getCurrentEditLogTxid though its in 
getInotifyEventStream ... I suppose it is given it actually does do 
getCurrentEditLogTxid

I think we should, since we want to know about this source of activity.  We 
want to know what the performance impact of inotify is.

I also fixed a findbugs warning.  Reposting

Is this intentional...  calling trace getCurrentEditLogTxid though its in

public DFSInotifyEventInputStream getInotifyEventStream() throws IOException {

Adding src/dst annotations is nice touch

Patch is great.
