------------------------------

I need to put back the bit where .tableinfo is made in a tmp dir.... Will make a new patch
later.

> This comes of HBASE-4547.  The rename in 0.20 hdfs fails if file exists already.  In
0.20+ its better but still 'some' issues if existing reader when file is renamed.  This issue
is about fixing this (though we depend on fix first being in hdfs).
