stack commented on HBASE-9976:
------------------------------
IIRC, there was an option in client to do full scan of meta table on startup.
Could do something like that in background rather than fetch the next ten under
a lock.
Patch lgtm. It is an improvement.
> Don't create duplicated TableName objects

> A profiling show that the table name is reponsible for 25% of the memory
> needed to keep the region locations. As well, comparisons will be faster if
> two identical table names are a single java object.
