+ <b>Should set MALLOC_ARENA_MAX in hadoop-config.sh</b><br>
+ <blockquote>New versions of glibc present in RHEL6 include a new arena allocator
design. In several clusters we've seen this new allocator cause huge amounts of virtual
memory to be used, since when multiple threads perform allocations, they each get their own
memory arena. On a 64-bit system, these arenas are 64M mappings, and the maximum number of
arenas is 8 times the number of cores. We've observed a DN process using 14GB of
vmem for only 300M of resident set. This causes all kinds of nasty issues fo...</blockquote></li>

+ <b>1.x: FSEditLog failure removes the wrong edit stream when storage dirs have
same name</b><br>
+ <blockquote>In {{FSEditLog.removeEditsForStorageDir}}, we iterate over the edits
streams trying to find the stream corresponding to a given dir. To check equality, we currently
use the following condition:<br>{code}<br> File parentDir = getStorageDirForStream(idx);<br>
if (parentDir.getName().equals(sd.getRoot().getName())) {<br>{code}<br>...
which is horribly incorrect. If two or more storage dirs happen to have the same terminal
path component (eg /data/1/nn and /data/2/nn) then it will pick the wrong strea...</blockquote></li>
