我已经在一台机器上安装了cloudera5的所有组件:name node、datanode、hue、pig、oozie、yarn、hbase。。。
我在shell中运行以下pig脚本:
sudo-u hdfs清管器
然后在Pig壳里跑
data = LOAD '/user/test/text.txt' as (text:CHARARRAY) ;
DUMP data;
脚本运行良好
但在查询编辑器/pig编辑器上运行此脚本时,它卡住了,下面是日志:

我已经使用了yarn utils脚本来支持我配置yarn-site.xml和marped-site.xml
python yarn-ulti.spy -c 6 -m 16 -d 1 -k True

剧本还挂着,心永远跳动着,谁来帮帮我吧!
这是我的配置:yarn-site.xml

pig应用程序提交了一个oozie作业,除了脚本所做的之外,它还将使用一个mr槽。
锁定通常是由于提交死锁造成的,比如gotcha#5或者集群中只有一个可用的任务槽。
