> During installation, first time it will try to suppress the HDFS shutdownhook
> by removing the hdfsclientfinalizer from HDFS. Since
> fs.hdfs.impl.disable.cache is enabled, so removal will be unsuccessful from
> HDFS (FS is not cached) and RuntimeException will be thrown with "Failed
> suppression of fs shutdown hook" message.
> In ShutdownHook,

> !ShutdownHookManager.deleteShutdownHook(hdfsClientFinalizer)) {
> throw new RuntimeException("Failed suppression of fs shutdown hook: " +
> hdfsClientFinalizer);
