启用DEBUG模式的Hive日志 –
突出显示的绿色异常.
根据我的理解,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.

在执行查询之前还要设置配置单元属性 –
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

更新1
根据这个答案 – LeaseExpiredException: No lease error on HDFS (Failed to close file),
我补充道
SET hive.exec.max.dynamic.partitions=100000;
SET hive.exec.max.dynamic.partitions.pernode=100000;
但后来也出现了同样的例外.
最佳答案 我解决了这个问题.让我详细解释一下.
即将发生的例外情况 –
> LeaveExpirtedException – 来自HDFS端.
> FileNotFoundException – 来自Hive端(当Tez执行引擎执行DAG时)
问题情景 –
>我们刚刚将hive版本从0.13.0升级到2.1.0.并且,以前的版本一切正常.零运行时异常.
解决问题的不同想法 –
>首先想到的是,由于NN智能,两个线程在同一块上工作.但按照以下设置
set mapreduce.map.speculative = false
set mapreduce.reduce.speculative = false
那是不可能的.
>然后,我将计数从1000增加到100000以进行以下设置 –
SET hive.exec.max.dynamic.partitions = 100000;
SET hive.exec.max.dynamic.partitions.pernode = 100000;
那也行不通.
>然后第三个想法是,绝对在同一个过程中,创建了mapper-1被另一个mapper / reducer删除了.但是,我们没有在Hveserver2,Tez日志中找到任何此类日志.
>最后,根本原因在于应用程序层代码本身.在hive-exec-2.1.0版本中,他们引入了新的配置属性
“hive.exec.stagingdir”：“蜂房升级.”
上述财产的描述 –
Directory name that will be created inside table locations in order to
support HDFS encryption. This is replaces ${hive.exec.scratchdir} for
query results with the exception of read-only tables. In all cases
${hive.exec.scratchdir} is still used for other temporary files, such
as job plans.
因此,如果应用程序层代码(ETL)中存在任何并发作业,并且正在同一个表上执行操作(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 –
>将元数据文件位置移动到外部表(表位于S3中).
>禁用HDFS加密(如stagingdir属性说明中所述.)
>更改为您的应用程序层代码以避免并发问题.
