> 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.
