----------------------------------
[~thiruvel] Thanks for reply.
I find that only the first time connect use the fixed order.
There is already a mechanism that promote random Metastore URI when reconnect.
(See promoteRandomMetaStoreURI() in reconnect method for detail.)
So shuffle at the creation phase is enough to make different client connect to
different Metastore.
