启用调试模式的配置单元日志-

在执行查询之前还要设置配置单元配置属性-

set hive.mapjoin.smalltable.filesize = 2000000000
set mapreduce.map.speculative = false
set mapreduce.output.fileoutputformat.compress = true
set hive.exec.compress.output = true

set 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

集群详情--

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

问题-

  1. 为什么抛出LeaseExpiredException？
  2. 配置单元查询失败是否与LeaseExpiredException有关？
  3. 是否因为配置单元配置属性错误？

更新-1

根据这个答案-leaseexpiredexception：HDFS上没有租约错误（关闭文件失败），

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

但也显示了同样的例外。

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-从HDFS端。
  2. FileNotFoundException-从配置单元端（当Tez执行引擎执行DAG时）
    null

然后，我将以下设置的计数从1000增加到100000-

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

那也没用。

并且，在我们的例子中，2个并发作业在同一个表上执行“插入覆盖”，这导致删除1个映射器的元数据文件，这是造成此问题的原因。

决议-

  1. 将元数据文件位置移到表外（表位于S3)。
  2. 禁用HDFS加密（如stagingdir属性说明中所述。）
  3. 更改应用程序层代码以避免并发问题。
