   Hi @mukul1987 ,   because some of MetadataStoreBuilder caller want the createIfMissing to be true, and some want it to be false.  Current implementaion caches the first "org.rocksdb.Options" instance for each configuration. Every next time caller gets the same createIfMissing, it's self createIfMissing  input is ignored. 
   
   For this "fail to crate Ratis container" case,  first time createIfMissing is "false", which will not create the directory for new containers, so the creation failed.
