Jean-Daniel Cryans updated HBASE-1892:
--------------------------------------
Attachment: HBASE-1892.patch
Little experiment trying to even further improve the splitting process.
Basically it opens the region right away and then tells the master. The HLog
thing I removed is because the debug was filling my disk, sorry.
Unfortunately, it's not faster. It takes a second to split, in the mean time
the client first notices that the region (under split) isn't served, then
refreshes once and the region server still didn't update .META., then it waits
one second and finally finds the new region.
> [performance] make hbase splits run faster
