Summary: Opencensus 0.28.0 bug with Distributed Tracing
Key: BEAM-14344
URL: https://issues.apache.org/jira/browse/BEAM-14344
Project: Beam
Issue Type: Test
Components: io-java-gcp
Affects Versions: 2.38.0, 2.37.0
Reporter: Thiago Nunes
Assignee: Thiago Nunes
Fix For: 2.39.0
Opencensus version 0.28.0 has an
[issue|https://github.com/census-instrumentation/opencensus-java/issues/2068]
that might crash internal threads when there is clock skew in the running
machine. This would cause threads to hang forever in a lock.
In the SpannerIO.readChangeStreams SDF, we are using opencensus to get
distributed tracing. Due to the bug above, we could reach a condition where a
close Span would never return, causing the job to get stuck.
This bug would only be present if the Connector was used alongside the faulty
version of the opencensus-impl dependency (<= 0.28.0), as the Apache Beam
project only depends on the opencensus-api.
Nevertheless, we would like to update the opencensus-api version to the newest
one (0.31.0), in order to avoid customer confusion.
