Lars Hofhansl commented on HBASE-4562:
--------------------------------------
Are the attached patches the full story?
I see only PONR moved, but no code to abort the server if timing out against
.META. Where is that code?
In the trunk patch the comment seems to be mangled. The big PONR comment be
moved above the comment speculating the that PONR should be moved here, just
like in the 0.90 and 0.92 patches...
In fact should that comment now be removed in all patches?
