> Right now, during upgrades datanode is processing all the storage dirs sequentially.
Assume it takes ~20 mins to process a single storage dir then  datanode which has ~10 disks
will take around 3hours to come up.
> *BlockPoolSliceStorage.java*
> {code}
>    for (int idx = 0; idx < getNumStorageDirs(); idx++) {
>       doTransition(datanode, getStorageDir(idx), nsInfo, startOpt);
>       assert getCTime() == nsInfo.getCTime() 
>           : "Data-node and name-node CTimes must be the same.";
>     }
> {code}
> It would save lots of time during major upgrades if datanode process all storagedirs/disks
parallelly.
> Can we make datanode to process all storage dirs parallelly?
