< h2 id = "为何使用-spark-on-kubernetes" > 为 何 使 用 spark on kubernetes< / h2 >
< p > 使 用 kubernetes原 生 调 度 的 spark on kubernetes是 对 现 有 的 spark on yarn/mesos的 资 源 使 用 方 式 的 革 命 性 的 改 进 , 主 要 表 现 在 以 下 几 点 : < / p >
< ol >
< li > Kubernetes原 生 调 度 : 不 再 需 要 二 层 调 度 , 直 接 使 用 kubernetes的 资 源 调 度 功 能 , 跟 其 他 应 用 共 用 整 个 kubernetes管 理 的 资 源 池 ; < / li >
< li > 资 源 隔 离 , 粒 度 更 细 : 原 先 yarn中 的 queue在 spark on kubernetes中 已 不 存 在 , 取 而 代 之 的 是 kubernetes中 原 生 的 namespace, 可 以 为 每 个 用 户 分 别 指 定 一 个 namespace, 限 制 用 户 的 资 源 quota; < / li >
< li > 细 粒 度 的 资 源 分 配 : 可 以 给 每 个 spark任 务 指 定 资 源 限 制 , 实 际 指 定 多 少 资 源 就 使 用 多 少 资 源 , 因 为 没 有 了 像 yarn那 样 的 二 层 调 度 ( 圈 地 式 的 ) , 所 以 可 以 更 高 效 和 细 粒 度 的 使 用 资 源 ; < / li >
< li > 监 控 的 变 革 : 因 为 做 到 了 细 粒 度 的 资 源 分 配 , 所 以 可 以 对 用 户 提 交 的 每 一 个 任 务 做 到 资 源 使 用 的 监 控 , 从 而 判 断 用 户 的 资 源 使 用 情 况 , 所 有 的 metric都 记 录 在 数 据 库 中 , 甚 至 可 以 为 每 个 用 户 的 每 次 任 务 提 交 计 量 ; < / li >
< li > 日 志 的 变 革 : 用 户 不 再 通 过 yarn的 web页 面 来 查 看 任 务 状 态 , 而 是 通 过 pod的 log来 查 看 , 可 将 所 有 的 kuberentes中 的 应 用 的 日 志 等 同 看 待 收 集 起 来 , 然 后 可 以 根 据 标 签 查 看 对 应 应 用 的 日 志 ; < / li >
< / ol >
< p > 所 有 这 些 变 革 都 可 以 让 我 们 更 高 效 的 获 取 资 源 、 更 有 效 率 的 获 取 资 源 ! < / p >

< h2 id = "spark-概念说明" > Spark 概 念 说 明 < / h2 >
< p > < a href = "http://spark.apache.org" target = "_blank" > Apache Spark< / a > 是 一 个 围 绕 速 度 、 易 用 性 和 复 杂 分 析 构 建 的 大 数 据 处 理 框 架 。 最 初 在 2009年 由 加 州 大 学 伯 克 利 分 校 的 AMPLab开 发 , 并 于 2010年 成 为 Apache的 开 源 项 目 之 一 。 < / p >
< p > 在 Spark 中 包 括 如 下 组 件 或 概 念 : < / p >
< ul >
< li > < strong > Application< / strong > : Spark Application 的 概 念 和 Hadoop 中 的 MapReduce 类 似 , 指 的 是 用 户 编 写 的 Spark 应 用 程 序 , 包 含 了 一 个 Driver 功 能 的 代 码 和 分 布 在 集 群 中 多 个 节 点 上 运 行 的 Executor 代 码 ; < / li >
< li > < strong > Driver< / strong > : Spark 中 的 Driver 即 运 行 上 述 Application 的 main() 函 数 并 且 创 建 SparkContext, 其 中 创 建 SparkContext 的 目 的 是 为 了 准 备 Spark应 用 程 序 的 运 行 环 境 。 在 Spark 中 由 SparkContext 负 责 和 ClusterManager 通 信 , 进 行 资 源 的 申 请 、 任 务 的 分 配 和 监 控 等 ; 当 Executor 部 分 运 行 完 毕 后 , Driver负 责 将 SparkContext 关 闭 。 通 常 用 SparkContext 代 表 Driver; < / li >
< li > < strong > Executor< / strong > : Application运 行 在 Worker 节 点 上 的 一 个 进 程 , 该 进 程 负 责 运 行 Task, 并 且 负 责 将 数 据 存 在 内 存 或 者 磁 盘 上 , 每 个 Application都 有 各 自 独 立 的 一 批 Executor。 在 Spark on Yarn模 式 下 , 其 进 程 名 称 为 < code > CoarseGrainedExecutorBackend< / code > , 类 似 于 Hadoop MapReduce 中 的 YarnChild。 一 个 < code > CoarseGrainedExecutorBackend< / code > 进 程 有 且 仅 有 一 个 executor 对 象 , 它 负 责 将 Task 包 装 成 taskRunner, 并 从 线 程 池 中 抽 取 出 一 个 空 闲 线 程 运 行 Task。 每 个 < code > CoarseGrainedExecutorBackend< / code > 能 并 行 运 行 Task 的 数 量 就 取 决 于 分 配 给 它 的 CPU 的 个 数 了 ; < / li >
< li > < strong > Cluster Manager< / strong > : 指 的 是 在 集 群 上 获 取 资 源 的 外 部 服 务 , 目 前 有 : < ul >
< li > Standalone: Spark原 生 的 资 源 管 理 , 由 Master负 责 资 源 的 分 配 ; < / li >
< li > Hadoop Yarn: 由 YARN中 的 ResourceManager负 责 资 源 的 分 配 ; < / li >
< / ul >
< / li >
< li > < strong > Worker< / strong > : 集 群 中 任 何 可 以 运 行 Application代 码 的 节 点 , 类 似 于 YARN中 的 NodeManager节 点 。 在 Standalone模 式 中 指 的 就 是 通 过 Slave文 件 配 置 的 Worker节 点 , 在 Spark on Yarn模 式 中 指 的 就 是 NodeManager节 点 ; < / li >
< li > < strong > 作 业 ( Job) < / strong > : 包 含 多 个 Task组 成 的 并 行 计 算 , 往 往 由 Spark Action催 生 , 一 个 JOB包 含 多 个 RDD及 作 用 于 相 应 RDD上 的 各 种 Operation; < / li >
< li > < strong > 阶 段 ( Stage) < / strong > : 每 个 Job会 被 拆 分 很 多 组 Task, 每 组 任 务 被 称 为 Stage, 也 可 称 TaskSet, 一 个 作 业 分 为 多 个 阶 段 , 每 一 个 stage的 分 割 点 是 action。 比 如 一 个 job是 : ( transformation1 -> transformation1 -> action1 -> transformation3 -> action2) , 这 个 job就 会 被 分 为 两 个 stage, 分 割 点 是 action1和 action2。 < / li >
< li > < p > < strong > 任 务 ( Task) < / strong > : 被 送 到 某 个 Executor上 的 工 作 任 务 ; < / p >
< / li >
< li > < p > < strong > Context< / strong > : 启 动 spark application的 时 候 创 建 , 作 为 Spark 运 行 时 环 境 。 < / p >
< / li >
< li > < strong > Dynamic Allocation( 动 态 资 源 分 配 ) < / strong > : 一 个 配 置 选 项 , 可 以 将 其 打 开 。 从 Spark1.2之 后 , 对 于 On Yarn模 式 , 已 经 支 持 动 态 资 源 分 配 ( Dynamic Resource Allocation) , 这 样 , 就 可 以 根 据 Application的 负 载 ( Task情 况 ) , 动 态 的 增 加 和 减 少 executors, 这 种 策 略 非 常 适 合 在 YARN上 使 用 spark-sql做 数 据 开 发 和 分 析 , 以 及 将 spark-sql作 为 长 服 务 来 使 用 的 场 景 。 Executor 的 动 态 分 配 需 要 在 cluster mode 下 启 用 " external shuffle service" 。 < / li >
< li > < strong > 动 态 资 源 分 配 策 略 < / strong > : 开 启 动 态 分 配 策 略 后 , application会 在 task因 没 有 足 够 资 源 被 挂 起 的 时 候 去 动 态 申 请 资 源 , 这 意 味 着 该 application现 有 的 executor无 法 满 足 所 有 task并 行 运 行 。 spark一 轮 一 轮 的 申 请 资 源 , 当 有 task挂 起 或 等 待 < code > spark.dynamicAllocation.schedulerBacklogTimeout< / code > (默 认 1s)时 间 的 时 候 , 会 开 始 动 态 资 源 分 配 ; 之 后 会 每 隔 < code > spark.dynamicAllocation.sustainedSchedulerBacklogTimeout< / code > (默 认 1s)时 间 申 请 一 次 , 直 到 申 请 到 足 够 的 资 源 。 每 次 申 请 的 资 源 量 是 指 数 增 长 的 , 即 1,2,4,8等 。 之 所 以 采 用 指 数 增 长 , 出 于 两 方 面 考 虑 : 其 一 , 开 始 申 请 的 少 是 考 虑 到 可 能 application会 马 上 得 到 满 足 ; 其 次 要 成 倍 增 加 , 是 为 了 防 止 application需 要 很 多 资 源 , 而 该 方 式 可 以 在 很 少 次 数 的 申 请 之 后 得 到 满 足 。 < / li >

< h2 id = "架构设计" > 架 构 设 计 < / h2 >
< p > 关 于 spark standalone 的 局 限 性 与 kubernetes native spark 架 构 之 间 的 区 别 请 参 考 Anirudh Ramanathan 在 2016年 10月 8日 提 交 的 issue < a href = "https://github.com/kubernetes/kubernetes/issues/34377" target = "_blank" > Support Spark natively in Kubernetes #34377< / a > 。 < / p >
< p > 简 而 言 之 , spark standalone on kubernetes 有 如 下 几 个 缺 点 : < / p >
< ul >
< li > 无 法 对 于 多 租 户 做 隔 离 , 每 个 用 户 都 想 给 pod 申 请 node 节 点 可 用 的 最 大 的 资 源 。 < / li >
< li > Spark 的 master/ worker 本 来 不 是 设 计 成 使 用 kubernetes 的 资 源 调 度 , 这 样 会 存 在 两 层 的 资 源 调 度 问 题 , 不 利 于 与 kuberentes 集 成 。 < / li >
< / ul >
< p > 而 kubernetes native spark 集 群 中 , spark 可 以 调 用 kubernetes API 获 取 集 群 资 源 和 调 度 。 要 实 现 kubernetes native spark 需 要 为 spark 提 供 一 个 集 群 外 部 的 manager 可 以 用 来 跟 kubernetes API 交 互 。 < / p >

< h3 id = "调度器后台" > 调 度 器 后 台 < / h3 >
< p > 使 用 kubernetes 原 生 调 度 的 spark 的 基 本 设 计 思 路 是 将 spark 的 driver 和 executor 都 放 在 kubernetes 的 pod 中 运 行 , 另 外 还 有 两 个 附 加 的 组 件 : < code > ResourceStagingServer< / code > 和 < code > KubernetesExternalShuffleService< / code > 。 < / p >
< p > Spark driver 其 实 可 以 运 行 在 kubernetes 集 群 内 部 ( cluster mode) 可 以 运 行 在 外 部 ( client mode) , executor 只 能 运 行 在 集 群 内 部 , 当 有 spark 作 业 提 交 到 kubernetes 集 群 上 时 , 调 度 器 后 台 将 会 为 executor pod 设 置 如 下 属 性 : < / p >
< ul >
< li > 使 用 我 们 预 先 编 译 好 的 包 含 kubernetes 支 持 的 spark 镜 像 , 然 后 调 用 < code > CoarseGrainedExecutorBackend< / code > main class 启 动 JVM。 < / li >
< li > 调 度 器 后 台 为 executor pod 的 运 行 时 注 入 环 境 变 量 , 例 如 各 种 JVM 参 数 , 包 括 用 户 在 < code > spark-submit< / code > 时 指 定 的 那 些 参 数 。 < / li >
< li > Executor 的 CPU、 内 存 限 制 根 据 这 些 注 入 的 环 境 变 量 保 存 到 应 用 程 序 的 < code > SparkConf< / code > 中 。 < / li >
< li > 可 以 在 配 置 中 指 定 spark 运 行 在 指 定 的 namespace 中 。 < / li >
