新搭建的FLINK集群出现的问题汇总
1.新搭建的Flink集群和Hadoop集群无法正常启动Flink任务 查看这个提交任务的日志无法发现有用的错误信息。
进一步查看yarn日志
发现只有JobManager的错误日志出现了如下的错误/bin/bash: /bin/java: No such file or directory。
正常情况下执行配置完成java之后,执行/bin/java的会出现如下的结果 根据查到的提示出现这个情况/bin/bash: /bin/java: No such file or directory的原因是软连接的问题。因此需要在每个节点都创建软连接ls -s /usr/java/jdk1.8.0_221 /bin/java
每个节点创建完软连接之后再次执行/bin/java结果如下 每个节点的软连接已生效再次提交任务成功。
概要
根據官方文檔配置在 $FLINK_HOME/lib 加入 flink-shaded-hadoop-3-uber-3.1.1.7.1.1.0-565-9.0.jar 經過驗證其實這個可以不加只加上下面的 hadoop classpath 就行。
或者在環境變量配置文件中 加入 hadoop classpath. ## 注意lib 後面一定要加 *export Hadoop_CLASSPATH$Hadoop_CLASSPATH:$HADOOP_HOME/lib/*export HADOOP_CLASSPATHhadoop classpath问题1

啟動 …/bin/yarn-session.sh 如何查看正在运行的Yarn容器的日志
众所周知flink on yarn 分为jobmanager的容器和taskmanager的容器。1.yarn application -list2.yarn applicationattempt -list ApplicationId3.yarn container -list Application AttemptId
到了这个第3步就能看到每个容器的访问的url 分别对应着jobmanager的和taskmanager的,但是具体怎么区分是哪个taskmanager的就只能依靠ip去区分。 htpp就用 curl 进行访问https就用curl -k进行访问。4.访问的结果包含了6种不同类型日志的访问路径找到我们想看的日志的访问路径然后访问访问路径的最后的参数-start-4096代表了显示多少日志出来。如果想查看完整的日志就应该把这个数调的很大5.为了查看方便应该使用 的方式把访问url的日志的结果输出到日志文件中。FLINK ON YARN提交方式详解 目前自己用到的yarn-per-job和yarn-applicaiton他们的执行方式是不同的执行yarn-per-job需要执行flink文件。同样的yarn-application也需要执行flik文件。./flink run -t yarn-per-job -d \
-p 1 \
-ynm test_env_job \
-yD rest.flamegraph.enabledtrue \
-yD jobmanager.memory.process.size1G \
-yD taskmanager.memory.process.size2G \
-yD taskmanager.numberOfTaskSlots1 \
-yD env.java.opts-Denvtest \
-c com.xingye.demo.TestTimer \
/cgroups_test/test/fk.jar./flink run-application -t yarn-application -d \
-p 5 \
-ynm test_impala_job \
-D rest.flamegraph.enabledtrue \
-D jobmanager.memory.process.size2G \
-D taskmanager.memory.process.size8G \
-D taskmanager.numberOfTaskSlots5 \
-c com.xingye.demo.ImpalaDemo1 \
/tmp/test_flink_impala/fk.jar通过两种命令的对比就发现区别
flink run -t yarn-per-job
flink run-application -t yarn-application还有需要注意的是 -y* 这个参数是特有的使用yarn的时候就能使用的参数也就是说yarn-per-job能用yarn-application也能用。-yD和-D动态参数的意思作用就是覆盖flink-conf.yaml文件中的默认配置。唯一不同的地方就在于-yD只能在使用yarn的时候指定动态参数不能在其他模式使用比如kubernetes无法使用-yD参数。-D可以在不同的方式下指定动态参数-D是一种更通用的指定动态参数的方式。总结yarn-per-job和yarn-application运行的都是同一个文件相同点在于都能使用yarn模式下特有的-y*的参数并且都能使用-D动态参数。
