hive - 当查询具有 GROUP BY 子句时，Hive 查询抛出“来自 org.apache.hadoop.hive.ql.exec.tez.TezTask 的代码 2”异常

问题描述

我在 HDP 3.1.4 上有 Hive + LLAP

Hive 和 Tez 配置是：

yarn.nodemanager.resource.memory-mb = 40960
yarn.scheduler.minimum-allocation-mb = 1024
yarn.scheduler.maximum-allocation-mb = 40960
hive.tez.container.size = 4096
num_llap_nodes=4
hive.llap.daemon.num.executors=8
hive.llap.daemon.yarn.container.mb = 35840
llap_headroom_space=2048
llap_heap_size=32768
hive.llap.io.memory.size=1024
tez.am.resource.memory.mb=4096
hive.tez.java.opts=-server -Djava.net.preferIPv4Stack=true -XX:NewRatio=8 -XX:+UseNUMA -XX:+UseG1GC -XX:+ResizeTLAB -XX:+PrintGCDetails -verbose:gc -XX:+PrintGCTimeStamps **-Xmx3276m**
tez.runtime.io.sort.mb= 1638
tez.runtime.unordered.output.buffer.size-mb=409

以下查询正常运行：

select count(*) from balance;

但是在以下查询中使用 group by 表达式时：

select count(*),jobdate from balance group by jobdate;

我已经尝试了很多配置，但是抛出了这个很长的异常：

解决方案

在 Ambari Hive Config 页面中设置hive.tez.container.size有两个部分。其中一个出现在SETTINGS选项卡中，另一个与 LLAP 相关的位于 ADVANCED 选项卡中的Advanced hive - interactive-site下。我正在尝试使用hive.tez.container.size值设置选项卡而不是高级 hive-interactive-site部分。最后，我设置了以下配置并解决了错误：

set hive.tez.container.size=10240;
set hive.tez.java.opts=-Xmx9216m;
set tez.runtime.io.sort.mb=3072;
set tez.runtime.unordered.output.buffer.size-mb=1024;
