----------------------------------------------------------
{quote}I assume in a normal deployment, we should not delete the meta znode?
The guys from AWS has a scenario where they restart a cluster with nothing on
zookeeper, then the problem is the InitMetaProcedure will delete the meta
region...
{quote}
yeah, 2.2.3 and branch-master InitMetaProcedure are different. the 2.2.3
InitMetaProcedure does not create metaTable, so master can resubmit
InitMetaProcedure. but in branch-master，master executes only
INIT_META_ASSIGN_META(if meta dir already exists, InitMetaProcedure should skip
INIT_META_WRITE_FS_LAYOUT and INIT_META_CREATE_NAMESPACES)
