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.
