Backend Changes

⛔ Breaking Changes

• Remove deprecated TLS flags (#2790, @albertteoh):

  • --cassandra.tls is replaced by --cassandra.tls.enabled
  • --cassandra-archive.tls is replaced by --cassandra-archive.tls.enabled
  • --collector.grpc.tls is replaced by --collector.grpc.tls.enabled
  • --collector.grpc.tls.client.ca is replaced by --collector.grpc.tls.client-ca
  • --es.tls is replaced by --es.tls.enabled
  • --es-archive.tls is replaced by --es-archive.tls.enabled
  • --kafka.consumer.tls is replaced by --kafka.consumer.tls.enabled
  • --kafka.producer.tls is replaced by --kafka.producer.tls.enabled
  • --reporter.grpc.tls is replaced by --reporter.grpc.tls.enabled

• Remove deprecated flags of Query Server --query.port and --query.host-port, please use dedicated HTTP --query.http-server.host-port (defaults to :16686) and gRPC --query.grpc-server.host-port (defaults to :16685) host-ports flags instead (#2772, @rjs211)

  • By default, if no flags are set, the query server starts on the dedicated ports. To use common port for gRPC and HTTP endpoints, the host-port flags have to be explicitly set

• Remove deprecated CLI flags (#2751, @LostLaser):

  • --collector.http-port is replaced by --collector.http-server.host-port
  • --collector.grpc-port is replaced by --collector.grpc-server.host-port
  • --collector.zipkin.http-port is replaced by --collector.zipkin.host-port

• Remove deprecated flags --health-check-http-port & --admin-http-port, please use --admin.http.host-port (#2752, @pradeepnnv)

• Remove deprecated flag --es.max-num-spans, please use --es.max-doc-count (#2482, @BernardTolosajr)

• Remove deprecated flag --jaeger.tags, please use --agent.tags (#2753, @yurishkuro)

• Remove deprecated Cassandra flags (#2789, @albertteoh):

  • --cassandra.enable-dependencies-v2 - Jaeger will automatically detect the version of the dependencies table
  • --cassandra.tls.verify-host - please use --cassandra.tls.skip-host-verify instead

• Remove incorrectly scoped downsample flags from the query service (#2782, @joe-elliott)

  • --downsampling.hashsalt removed from jaeger-query
  • --downsampling.ratio removed from jaeger-query

New Features

• Add TLS Support for gRPC and HTTP endpoints of the Query and Collector servers (#2337, #2772, #2798, @rjs211)

  • If TLS in enabled on either or both of gRPC or HTTP endpoints, the gRPC host-port and the HTTP host-port have to be different
  • If TLS is disabled on both endpoints, common HTTP and gRPC host-port can be explicitly set using the following host-port flags respectively:
    • Query: --query.http-server.host-port and --query.grpc-server.host-port
    • Collector: --collector.http-server.host-port and --collector.grpc-server.host-port

• Add support for Kafka SASL/PLAIN authentication via SCRAM-SHA-256 or SCRAM-SHA-512 mechanism (#2724, @WalkerWang731)

• [agent] Add metrics to show connections status between agent and collectors (#2657, @WalkerWang731)

• Add plaintext as a supported kafka auth option (#2721, @pdepaepe)

• Add ability to use JS file for UI configuration (#123 from jaeger-ui) (#2707, @th3M1ke)

• Support Elasticsearch ILM for managing jaeger indices (#2796, @bhiravabhatla)

• Push official images to quay.io, in addition to Docker Hub (#2783, @Ashmita152)

• Add status command (#2684, @sniperking1234)

  • Usage:

    $ ./cmd/collector/collector-darwin-amd64 status
    {"status":"Server available","upSince":"2021-02-19T17:57:12.671902+11:00","uptime":"25.241233383s"}
    

• Support configurable date separator for Elasticsearch index names (#2637, @sniperking1234)

• Copy spans from memory store (#2720, @bobrik)
• [pkg/queue] Add StartConsumersWithFactory function (#2714, @mx-psi)
• Fix potential cross-site scripting issue (#2697, @yurishkuro)
