org.apache.hadoop.mapreduce.counters.LimitExceededException:太多计数器:121 max = 120 [英] org.apache.hadoop.mapreduce.counters.LimitExceededException: Too many counters: 121 max=120
问题描述
我得到如下错误:
org.apache。
我正在运行一个hadoop作业(来自oozie),它有很少的计数器和多输出。 hadoop.mapreduce.counters.LimitExceededException:计数器太多:121 max = 120
然后我删除了所有有计数器的代码,并且将mout.setCountersEnabled设置为false。
并且将hadoop配置中的最大计数器设置为240.
现在我仍然得到相同的错误
org.apache.hadoop.mapreduce。 counters.LimitExceededException:计数器太多:241 max = 240
我该如何解决这个问题?
是否有任何隐藏计数器存在的可能性?
我怎样才能清楚之前有什么柜台超过240?(这个过程看起来像停止之前,我可以打印任何东西?)
谢谢,
Xinsong 解决方案我使用以下方法解决了这个问题:
vi $ HADOOP_HOME / conf / mapred-site.xml p>
<属性>
<名称> mapreduce.job.counters.limit< / name>
<! - <值> 120< /值> - >
<值> 20000< /值>
< description>限制每个作业允许的计数器数量。默认值是200.< / description>
< / property>
I'm running a hadoop job ( from oozie ) that has few counters, and multioutput.
I get error like: org.apache.hadoop.mapreduce.counters.LimitExceededException: Too many counters: 121 max=120
Then I removed all the code that has counters, and also set mout.setCountersEnabled to false. And also set the max counters to 240 in hadoop config.
Now I still get the same error org.apache.hadoop.mapreduce.counters.LimitExceededException: Too many counters: 241 max=240
How can I solve this problem? Is there any possibility that any hidden counters exists? How can I make clear what counters there before exceeds 240 ? (The process looks like stopped before I can print anything? )
Thanks, Xinsong
I solved the problem use the following method: vi $HADOOP_HOME/conf/mapred-site.xml
<property>
<name>mapreduce.job.counters.limit</name>
<!--<value>120</value>-->
<value>20000</value>
<description>Limit on the number of counters allowed per job. The default value is 200.</description>
</property>
