Its not clear from hbase-3904 what the issues are. If there's some code
relying on isTableAvailable, that code is inherently broken.

1. isTableAvailable() is never reliable, because
     (a) if it returns true, the table can disappear immediately after the
call finishes, or
     (b) the table can appear immediately after the call returns false

2. In the normal situation, where some RS's could be down (while most are
up), it would be correct for  isTableAvailable() to return true. But the
caller cannot rely on it unless they do a get() on the row they are
interested in.

Ted, could you explain your concern?
