Ted Yu commented on HBASE-2256:
-------------------------------
{code}
long l = System.nanoTime();
long l2 = System.currentTimeMillis();
{code}
Looking at the values of l (1302209826865074000) and l2 (1302209826865),
nanoTime is aligned with time in millis.
Assuming nano and milli timestamps correlate, we can devise (correction)
mechanism in master and region servers such that (corrected) nano timestamp
reflects the actual millisecond timestamp.
> Delete row, followed quickly to put of the same row will sometimes fail.
