记录博主第一次使用Flink SQL查询Hive的配置以及问题解决过程
博主目前还没有用过Flink,没有写过Flink代码，完全是一个小白。之所以使用Flink，是因为博主目前需要测试使用dolphinscheduler的一些功能，其中包括Flink数据源，这里Flink数据源我们使用的是Kyuubi Flink Engine,且学会、了解了Flink之后对于学习Hudi、Kyuubi也是有帮助的。
flink-1.14.3，这里使用kyuubi1.5.2自带的Flink
HDP环境，Hadoop、Hive等已经安装配置好
export HADOOP_CLASSPATH=hadoop classpath
可以添加在比如/ect/profile里，这样等于修改全局的环境，如果想只对Flink生效，可以添加在bin/config.sh文件里
一开始我对hadoop classpath理解错了，以为是自己手动修改成实际的路径，但是hadoop对应的jar包的路径有很多，后来发现它的意思是执行命令hadoop classpath将返回值赋给HADOOP_CLASSPATH
hadoop classpath /usr/hdp/3.1.0.0-78/hadoop/conf:/usr/hdp/3.1.0.0-78/hadoop/lib/*:/usr/hdp/3.1.0.0-78/hadoop/.//*:/usr/hdp/3.1.0.0-78/hadoop-hdfs/./:/usr/hdp/3.1.0.0-78/hadoop-hdfs/lib/*:/usr/hdp/3.1.0.0-78/hadoop-hdfs/.//*:/usr/hdp/3.1.0.0-78/hadoop-mapreduce/lib/*:/usr/hdp/3.1.0.0-78/hadoop-mapreduce/.//*:/usr/hdp/3.1.0.0-78/hadoop-yarn/./:/usr/hdp/3.1.0.0-78/hadoop-yarn/lib/*:/usr/hdp/3.1.0.0-78/hadoop-yarn/.//*:/usr/hdp/3.1.0.0-78/tez/*:/usr/hdp/3.1.0.0-78/tez/lib/*:/usr/hdp/3.1.0.0-78/tez/conf:/usr/hdp/3.1.0.0-78/tez/conf_llap:/usr/hdp/3.1.0.0-78/tez/doc:/usr/hdp/3.1.0.0-78/tez/hadoop-shim-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/hadoop-shim-2.8-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/lib:/usr/hdp/3.1.0.0-78/tez/man:/usr/hdp/3.1.0.0-78/tez/tez-api-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-common-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-dag-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-examples-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-history-parser-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-javadoc-tools-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-job-analyzer-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-mapreduce-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-protobuf-history-plugin-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-runtime-internals-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-runtime-library-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-tests-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-yarn-timeline-cache-plugin-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-yarn-timeline-history-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-yarn-timeline-history-with-acls-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/tez-yarn-timeline-history-with-fs-0.9.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/ui:/usr/hdp/3.1.0.0-78/tez/lib/async-http-client-1.9.40.jar:/usr/hdp/3.1.0.0-78/tez/lib/commons-cli-1.2.jar:/usr/hdp/3.1.0.0-78/tez/lib/commons-codec-1.4.jar:/usr/hdp/3.1.0.0-78/tez/lib/commons-collections-3.2.2.jar:/usr/hdp/3.1.0.0-78/tez/lib/commons-collections4-4.1.jar:/usr/hdp/3.1.0.0-78/tez/lib/commons-io-2.4.jar:/usr/hdp/3.1.0.0-78/tez/lib/commons-lang-2.6.jar:/usr/hdp/3.1.0.0-78/tez/lib/commons-math3-3.1.1.jar:/usr/hdp/3.1.0.0-78/tez/lib/gcs-connector-1.9.10.3.1.0.0-78-shaded.jar:/usr/hdp/3.1.0.0-78/tez/lib/guava-11.0.2.jar:/usr/hdp/3.1.0.0-78/tez/lib/hadoop-aws-3.1.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/lib/hadoop-azure-3.1.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/lib/hadoop-azure-datalake-3.1.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/lib/hadoop-hdfs-client-3.1.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/lib/hadoop-mapreduce-client-common-3.1.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/lib/hadoop-mapreduce-client-core-3.1.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/lib/hadoop-yarn-server-timeline-pluginstorage-3.1.1.3.1.0.0-78.jar:/usr/hdp/3.1.0.0-78/tez/lib/jersey-client-1.19.jar:/usr/hdp/3.1.0.0-78/tez/lib/jersey-json-1.19.jar:/usr/hdp/3.1.0.0-78/tez/lib/jettison-1.3.4.jar:/usr/hdp/3.1.0.0-78/tez/lib/jetty-server-9.3.22.v20171030.jar:/usr/hdp/3.1.0.0-78/tez/lib/jetty-util-9.3.22.v20171030.jar:/usr/hdp/3.1.0.0-78/tez/lib/jsr305-3.0.0.jar:/usr/hdp/3.1.0.0-78/tez/lib/metrics-core-3.1.0.jar:/usr/hdp/3.1.0.0-78/tez/lib/protobuf-java-2.5.0.jar:/usr/hdp/3.1.0.0-78/tez/lib/RoaringBitmap-0.4.9.jar:/usr/hdp/3.1.0.0-78/tez/lib/servlet-api-2.5.jar:/usr/hdp/3.1.0.0-78/tez/lib/slf4j-api-1.7.10.jar:/usr/hdp/3.1.0.0-78/tez/lib/tez.tar.gz
flink-connector-hive 下载地址：https://repo1.maven.org/maven2/org/apache/flink/flink-connector-hive_2.12/1.14.3/，对应flink-connector-hive_2.12-1.14.3.jarhive-exec: 从HIVE_HOME/lib拷贝即可： hive-exec-3.1.0.3.1.0.0-78.jarlibfb303: 从HIVE_HOME/lib拷贝即可：libfb303-0.9.3.jar将这几个包放到
Flink具有多种提交方式，比如：常用的local模式，stantalone模式，yarn模式，k8s等。sql client 默认为stantalone模式,我们可以根据自己的需求选择对应的模式
这是默认的模式，什么配置参数都不用修改，不过stantalone模式，需要先使用bin/start-cluster.sh命令启动stantalone集群
停止stantalone集群:bin/stop-cluster.sh
修改flink-conf.yaml 添加：
execution.target: yarn-per-job
bin/yarn-session.sh -nm flink-sql -d
相关参数：
bin/yarn-session.sh -h
Usage:
Optional
-at,--applicationType <arg> Set a custom application type for the application on YARN
-D <property=value> use value for given property
-d,--detached If present, runs the job in detached mode
-h,--help Help for the Yarn session CLI.
-id,--applicationId <arg> Attach to running YARN session
-j,--jar <arg> Path to Flink jar file
-jm,--jobManagerMemory <arg> Memory for JobManager Container with optional unit (default: MB)
-m,--jobmanager <arg> Set to yarn-cluster to use YARN execution mode.
-nl,--nodeLabel <arg> Specify YARN node label for the YARN application
-nm,--name <arg> Set a custom name for the application on YARN
-q,--query Display available YARN resources (memory, cores)
-qu,--queue <arg> Specify YARN queue.
-s,--slots <arg> Number of slots per TaskManager
-t,--ship <arg> Ship files in the specified directory (t for transfer)
-tm,--taskManagerMemory <arg> Memory per TaskManager Container with optional unit (default: MB)
-yd,--yarndetached If present, runs the job in detached mode (deprecated; use non-YARN specific option instead)
-z,--zookeeperNamespace <arg> Namespace to create the Zookeeper sub-paths for high availability mode In order to stop Flink gracefully, use the following command: $ echo "stop" | ./bin/yarn-session.sh -id application_1661394335976_0016 If this should not be possible, then you can also kill Flink via YARN's web interface or via: $ yarn application -kill application_1661394335976_0016 Note that killing Flink might not clean up all job artifacts and temporary files.
成功启动yarn-session后，可以在yarn ui界面看到 (点击Tracking UI中的 ApplicationMaster，可以进入到flink的管理界面)
除了要修改execution.target为yarn-session外，还要添加yarn.application.id，值为yarn对应的id
execution.target: yarn-session yarn.application.id: application_1661394335976_0013
bin/sql-client.sh

记录问题解决过程
创建Hive catalog时
[ERROR] Could not execute SQL statement. Reason: java.lang.ClassNotFoundException: org.apache.hadoop.fs.FSDataInputStream
解决方法：export HADOOP_CLASSPATH=hadoop classpath
[ERROR] Could not execute SQL statement. Reason: java.lang.ClassNotFoundException: org.apache.hive.common.util.HiveVersionInfo
解决方法：hive-exec: 从$HIVE_HOME/lib拷贝即可： hive-exec-3.1.0.3.1.0.0-78.jar
[ERROR] Could not execute SQL statement. Reason: org.apache.flink.table.catalog.exceptions.CatalogException: Failed to create Hive Metastore client
这个异常，在sql客户度看不到详细的信息，不知道缺哪个包
解决方法，查看日志：log/flink-root-sql-client-*.log，找到对应异常

... 12 more 根据异常信息无法判断原因，查找yanr-session相关资料，发现缺少配置：
yarn.application.id: application_1661394335976_0013
[ERROR] Could not execute SQL statement. Reason: java.lang.ClassNotFoundException: org.apache.hadoop.mapred.JobConf
具体表现为yarn-session能够启动成功，但是在执行sql时报上面的错误，所以一开始并不会想到之和yarn-session服务有关，因为在其他模式通过设置了HADOOP_CLASSPATH之后是可以正常执行查询sql的，最后才想到是不是和yarn-session服务有关
解决方法:
将 hadoop-mapreduce-client-core-3.1.1.3.1.0.0-78.jar 拷贝到 flink/lib目录下，并重启yarn-session，这里注意重启yarn-session后需要同步更新yarn.application.id的值，然后验证sql果然没有问题了
具体是使用hive 方言建表时：
