Release 1.6: 2022-12-24

MR3

  • Support capacity scheduling with mr3.dag.queue.capacity.specs and mr3.dag.queue.name.

Release 1.5: 2022-7-24

MR3

  • Use liveness probes on ContainerWorker Pods running separate processes for shuffle handlers.
  • When a ContainerGroup is removed, all its Prometheus metrics are removed.

  • DAGAppMaster stops if it fails to contact Timeline Server during initialization.
  • Introduce mr3.k8s.master.pod.cpu.limit.multiplier for a multiplier for the CPU resource limit for DAGAppMaster Pods.

  • Introduce mr3.application.tags and mr3.application.scheduling.properties.map.
  • The logic for speculative execution uses the average execution time of Tasks (instead of the maximum execution time).

Hive on MR3

  • DistCp jobs are sent to MR3, not to Hadoop. As a result, DistCp runs okay on Kubernetes.
  • org.apache.tez.common.counters.Limits is initialized in HiveServer2.

  • Introduce mr3.container.max.num.workers to limit the number of ContainerWorkers.
  • Introduce mr3.k8s.pod.worker.node.affinity.specs to specify node affinity for ContainerWorker Pods.
  • No longer use mr3.convert.container.address.host.name.
  • Support ContainerWorker recycling (which is different from ContainerWorker reuse) with mr3.container.scheduler.scheme.
  • Introduce mr3.am.task.no.retry.errors to specify the names of errors that prevent the re-execution of Tasks (e.g., OutOfMemoryError,MapJoinMemoryExhaustionError).

  • DAGAppMaster correctly reports to MR3Client the time from DAG submission to DAG execution.
  • Introduce mr3.container.localize.python.working.dir.unsafe to localize Python scripts in working directories of ContainerWorkers. Localizing Python scripts is an unsafe operation: 1) Python scripts are shared by all DAGs; 2) once localized, Python scripts are not deleted.
  • The image pull policy specified in mr3.k8s.pod.image.pull.policy applies to init containers as well as ContainerWorker containers.
  • Introduce mr3.auto.scale.out.num.initial.containers which specifies the number of new ContainerWorkers to create in a scale-out operation when no ContainerWorkers are running.

  • Introduce hive.mr3.llap.orc.memory.per.thread.mb to specify the memory allocated to each ORC manager in low-level LLAP I/O threads.

Spark on MR3

  • Initial release

Release 1.2: 2020-10-26

MR3

  • Introduce mr3.k8s.pod.worker.init.container.command to execute a shell command in a privileged init container.
  • Introduce mr3.k8s.pod.master.toleration.specs and mr3.k8s.pod.worker.toleration.specs to specify tolerations for DAGAppMaster and ContainerWorker Pods.
  • Setting mr3.dag.queue.scheme to individual properly implements fair scheduling among concurrent DAGs.
  • Introduce mr3.k8s.pod.worker.additional.hostpaths to mount additional hostPath volumes.
  • mr3.k8s.worker.total.max.memory.gb and mr3.k8s.worker.total.max.cpu.cores work okay when autoscaling is enabled.
  • DAGAppMaster and ContainerWorkers can publish Prometheus metrics.
  • The default value of mr3.container.task.failure.num.sleeps is 0.
  • Reduce the log size of DAGAppMaster and ContainerWorker.
  • TaskScheduler can process about twice as many events (TaskSchedulerEventTaskAttemptFinished) per unit time as in MR3 1.1, thus doubling the maximum cluster size that MR3 can manage.
  • Optimize the use of CodecPool shared by concurrent TaskAttempts.
  • The getDags command of MasterControl prints both IDs and names of DAGs.
  • On Kubernetes, the updateResourceLimit command of MasterControl updates the limit on the total resources for all ContainerWorker Pods. The user can further improve resource utilization when autoscaling is enabled.

  • Hive expands all system properties in configuration files (such as core-site.xml) before passing to MR3.

  • MR3 creates three ServiceAccounts: 1) for Metastore and HiveSever2 Pods; 2) for DAGAppMaster Pod; 3) for ContainerWorker Pods. The user can use IAM roles for ServiceAccounts.
  • Docker containers start as root. In kubernetes/env.sh, DOCKER_USER should be set to root and the service principal name in HIVE_SERVER2_KERBEROS_PRINCIPAL should be root.
  • Support Ranger 2.0.0 and 2.1.0.

Release 1.1: 2020-7-19

MR3

  • Support DAG scheduling schemes (specified by mr3.dag.queue.scheme).
  • Optimize DAGAppMaster by freeing memory for messages to Tasks when fault tolerance is disabled (with mr3.am.task.max.failed.attempts set to 1).
  • Fix a minor memory leak in DaemonTask (which also prevents MR3 from running more than 2^30 DAGs when using the shuffle handler).
  • Improve the chance of assigning TaskAttempts to ContainerWorkers that match location hints.
  • TaskScheduler can use location hints produced by ONE_TO_ONE edges.
  • TaskScheduler can use location hints from HDFS when assigning TaskAttempts to ContainerWorker Pods on Kubernetes (with mr3.convert.container.address.host.name).
  • Introduce mr3.k8s.pod.cpu.cores.max.multiplier to specify the multiplier for the limit of CPU cores.
  • Introduce mr3.k8s.pod.memory.max.multiplier to specify the multiplier for the limit of memory.
  • Introduce mr3.k8s.pod.worker.security.context.sysctls to configure kernel parameters of ContainerWorker Pods using init containers.
  • Support speculative execution of TaskAttempts (with mr3.am.task.concurrent.run.threshold.percent).
  • A ContainerWorker can run multiple shuffle handlers each with a different port. The configuration key mr3.use.daemon.shufflehandler now specifies the number of shuffle handlers in each ContainerWorker.
  • With speculative execution and the use of multiple shuffle handlers in a single ContainerWorker, fetch delays rarely occur.
  • A ContainerWorker Pod can run shuffle handlers in a separate container (with mr3.k8s.shuffle.process.ports).
  • On Kubernetes, DAGAppMaster uses ReplicationController instead of Pod, thus making recovery much faster.
  • On Kubernetes, ConfigMaps mr3conf-configmap-master and mr3conf-configmap-worker survive MR3, so the user should delete them manually.
  • Java 8u251/8u252 can be used on Kubernetes 1.17 and later.

Hive on MR3

  • CrossProductHandler asks MR3 DAGAppMaster to set TEZ_CARTESIAN_PRODUCT_MAX_PARALLELISM (Cf. HIVE-16690, Hive 3/4).
  • Hive 4 on MR3 is stable (currently using 4.0.0-SNAPSHOT).
  • No longer support Hive 1.
  • Ranger uses a local directory (emptyDir volume) for logging.
  • The open file limit for Solr (in Ranger) is not limited to 1024.
  • HiveServer2 and DAGAppMaster create readiness and liveness probes.

Release 1.0: 2020-2-17

MR3

  • Support DAG priority schemes (specified by mr3.dag.priority.scheme) and Vertex priority schemes (specified by mr3.vertex.priority.scheme).
  • Support secure shuffle (using SSL mode) without requiring separate configuration files.
  • ContainerWorker tries to avoid OutOfMemoryErrors by sleeping after a TaskAttempt fails (specified by mr3.container.task.failure.num.sleeps).
  • Errors from InputInitializers are properly passed to MR3Client.
  • MasterControl supports two new commands for gracefully stopping DAGAppMaster and ContainerWorkers.

Hive on MR3

  • Allow fractions for CPU cores (with hive.mr3.resource.vcores.divisor).
  • Support rolling updates.
  • Hive on MR3 can access S3 using AWS credentials (with or without Helm).
  • On Amazon EKS, the user can use S3 instead of PersistentVolumes on EFS.

  • DAGAppMaster recovers from OutOfMemoryErrors due to the exhaustion of threads.

Hive on MR3

  • Compaction sends DAGs to MR3, instead of MapReduce, when hive.mr3.compaction.using.mr3 is set to true.
