> h2. Problem
> When using OSS in 1.17, an exception will be thrown:
> {code:java}
> java.lang.NoClassDefFoundError:
> org/apache/hadoop/thirdparty/com/google/common/base/Preconditions
> at

> at org.apache.flink.core.fs.Path.getFileSystem(Path.java:274){code}
> It could be reproduced in ITCASE of OSS if some envs has been configured.
> h2. Why
> After https://issues.apache.org/jira/browse/FLINK-27308 and
> https://issues.apache.org/jira/browse/FLINK-29502 ，hadoop-aliyun has also be
> upgraded to 3.3.4 which relys on the newest version of hadoop-common.
> OSS still uses the old version (2.10.2) extended from flink-parent so that
> some classes cannot be found.
