Three improvements according to our production use experience:

  • fix compatible problem when use apache as storage node server.
  • fix false positive test failure
  • Take a more acceptable balance between space and cpu/io utilization when allocating new file.

fid size workaround for apache 2.x
50a4c03 
Apache doesn't return a Content-Length header for zero byte files. So we add a
specific workaround for it. If it's not apache, we should still throw errors if
that header is missing.

Be patient to let the rebalance test pass

The original iteration value causes the rebalance test failure on some low
level box.

Spread new writing file to more disks
f6df390 
Mogilefs only consider space balance when allocates new file. The behavior
causes cpu and io hotspot on new add disks, and is significant for a busy
cluster. This modification try to take a more acceptable balance between space
and cpu/io utilization.
