這種問題一般發生在將flink程序部署到yarn集羣的時候，由於flink啓動的時候會加載hadoop下面的jar包，加到自己的classpath下面，如果hadoop的jar包和自己flink工程的jar包版本不一致就會導致這個問題，解決辦法：排除自己工程中的hadoop相關的jar,打包的時候不要打進來.
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>${hadoop.version}</version>
<scope>provided</scope>
</dependency>
提示，有可能你沒有顯式的引入hadoop-common、hadoop-hdfs這樣的jar包，但是你引入了hbase的jar包，因爲hbase會引入hdfs相關的jar包，也會導致類似的錯誤。
local class incompatible
org.apache.flink.table.api.StreamQueryConfig; local class incompatible: stream classdesc serialVersionUID = XXX, local class serialVersionUID = -XXX
在提交flink程序的時候如果出現這種情況一般是由於jar包衝突導致的，可能是某一個jar的衝突、也可能是scala的版本不一致導致的，比如你的flink集羣的scala是2.11，你的程序的scala版本是2.12
