启用 DEBUG 模式的 Hive 日志 -

以绿色突出显示的异常。

据我了解，就在异常之前，它将文件名替换为其他名称，所有这些都发生在 S3 中。因为，S3 最终是一致的，这就是为什么有时它会显示这个异常，有时它会工作文件。

https://docs.google.com/document/d/1cwXVqQ3p-xPFcBqU9AuD7C8z8rHjhUIHwPjY-nVpFK0/edit?usp=sharing

在执行查询之前还要设置 hive 配置属性 -

set hive.mapjoin.smalltable.filesize = 2000000000
set mapreduce.map.speculative = false
set mapreduce.output.fileoutputformat.compress = true
set hive.exec.compress.output = true
set mapreduce.task.timeout = 6000000
set hive.optimize.bucketmapjoin.sortedmerge = true
set io.compression.codecs = org.apache.hadoop.io.compress.GzipCode
set hive.auto.convert.sortmerge.join.noconditionaltask = false
set hive.optimize.bucketmapjoin = true
set hive.exec.compress.intermediate = true
set hive.enforce.bucketmapjoin = true
set mapred.output.compress = true
set mapreduce.map.output.compress = true
set hive.auto.convert.sortmerge.join = false
set hive.auto.convert.join = false
set mapreduce.reduce.speculative = false
set mapred.output.compression.codec = org.apache.hadoop.io.compress.GzipCodec
set hive.cache.expr.evaluation=false
set mapred.output.compress=true
set hive.exec.compress.output=true
set mapred.output.compression.codec=org.apache.hadoop.io.compress.GzipCodec
set io.compression.codecs=org.apache.hadoop.io.compress.GzipCodec
set hive.exec.compress.intermediate=true
set mapreduce.map.output.compress=true
set hive.auto.convert.join=false
set mapreduce.map.speculative=false
set mapreduce.reduce.speculative=false

集群详情 -

  1. 一个具有 32 GB 磁盘空间的数据节点。
  2. Hive - 2.1.0，执行引擎 - tez 0.8.3
  3. Hadoop - 2.7.2

问题-

  1. 为什么会抛出 LeaseExpiredException ？
  2. 是否与 LeaseExpiredException 相关的 Hive 查询失败？
  3. 是因为错误的配置单元配置属性吗？

更新 1

根据这个答案 - LeaseExpiredException: No lease error on HDFS (Failed to close file)，

我添加了

SET hive.exec.max.dynamic.partitions=100000; 
SET hive.exec.max.dynamic.partitions.pernode=100000;

但随后也显示出同样的异常。

我解决了这个问题。让我详细解释一下。

即将到来的例外 -

  1. LeaveExpirtedException - 来自 HDFS 方面。
  2. FileNotFoundException - 从 Hive 端（当 Tez 执行引擎执行 DAG 时）

问题场景——

  1. 我们刚刚将 hive 版本从 0.13.0 升级到了 2.1.0。而且，在以前的版本中一切正常。零运行时异常。

解决问题的不同想法 -

  1. 首先想到的是，由于 NN 智能，两个线程正在处理同一块。但根据以下设置

    设置 mapreduce.map.speculative=false 设置 mapreduce.reduce.speculative=false

那是不可能的。

  1. 然后，对于以下设置，我将计数从 1000 增加到 100000 -

    设置 hive.exec.max.dynamic.partitions=100000; 设置 hive.exec.max.dynamic.partitions.pernode=100000;

那也没有用。

  1. 然后第三个想法是，肯定是在同一个过程中，创建的 mapper-1 被另一个 mapper/reducer 删除了。但是，我们在 Hveserver2、Tez 日志中没有发现任何此类日志。

  2. 最后，根本原因在于应用层代码本身。在 hive-exec-2.1.0 版本中，他们引入了新的配置属性

    “hive.exec.stagingdir”：“.hive-staging”

上述属性的描述 -

将在表位置内创建的目录名称，以支持 HDFS 加密。这将替换 ${hive.exec.scratchdir} 的查询结果，只读表除外。在所有情况下，${hive.exec.scratchdir} 仍用于其他临时文件，例如作业计划。

因此，如果应用层代码 (ETL) 中有任何并发​​作业，并且正在同一张表上执行操作（重命名/删除/移动），则可能会导致此问题。

而且，在我们的例子中，2 个并发作业在同一个表上执行“INSERT OVERWRITE”，这导致删除 1 个映射器的元数据文件，这导致了这个问题。

解析度 -

  1. 将元数据文件位置移动到表外（表位于 S3 中）。
  2. 禁用 HDFS 加密（如 stagingdir 属性的描述中所述。）
  3. 更改为您的应用程序层代码以避免并发问题。
