Let's wait what it will say.
Hi, @Hexiaoqiao Thank you very much for your help in reviewing the code. I
read the compilation report carefully and can confirm that the compilation
error of java doc has nothing to do with this pr.
java doc has become more strict in the compilation environment of jdk11,
java doc will be run 2 times after a pr commit.
1st run
Compile the code of the current trunk directly，We can see the following
report.
[hadoop-hdfs in trunk failed with JDK Private
Build-11.0.15+10-Ubuntu-0ubuntu0.20.04.1.]([/branch-javadoc-hadoop-hdfs-project_hadoop-hdfs-jdkPrivateBuild-11.0.15+10-Ubuntu-0ubuntu0.20.04.1.txt](https://ci-hadoop.apache.org/job/hadoop-multibranch/job/PR-4419/4/artifact/out/branch-javadoc-hadoop-hdfs-project_hadoop-hdfs-jdkPrivateBuild-11.0.15+10-Ubuntu-0ubuntu0.20.04.1.txt))
2nd run
Compile and run after merge pr，We can see the following report.
[hadoop-hdfs in the patch failed with JDK Private
Build-11.0.15+10-Ubuntu-0ubuntu0.20.04.1.](https://ci-hadoop.apache.org/job/hadoop-multibranch/job/PR-4419/4/artifact/out/patch-javadoc-hadoop-hdfs-project_hadoop-hdfs-jdkPrivateBuild-11.0.15+10-Ubuntu-0ubuntu0.20.04.1.txt)
In 2 runs will report the following error
```

```
I try to fix it in this pr(https://github.com/apache/hadoop/pull/4423),
after solving the error, the java doc can be compiled successfully with jdk11.
