> 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.

> !ShutdownHookManager.deleteShutdownHook(hdfsClientFinalizer)) {

> hdfsClientFinalizer);
