Work Description: xiaoyuyao commented on issue #641: HDDS-1318. Fix
MalformedTracerStateStringException on DN logs. Contributed by Xiaoyu Yao.
URL: https://github.com/apache/hadoop/pull/641#issuecomment-477369914
The current pattern of export and import traceID over the wire (GRPC/Ratis)
is via the TraceID in the protocol message. But this changed the original
traceID which the test expect to be the same, which is not true with the new
yaeger based tracing where the parent:children:... are appended along the
invocation chain. Will remove the invalid verification from those tests, cc:
@elek .
