> This is particularly problematic because of the quoting required to examine hdfs paths
with a "!" character in them. The root table ID and the metadata table ID should not use special
characters.
> Some considerations:
> # should not collide with possible user table IDs
> # might be useful, but may not be necessary, to retain lexicographical sort order, so
root table goes first, then metadata table, then other tables
> Some options:
> # Use negative numbers: -1 for the root table, -2 for the metadata table (my personal
favorite)
> # Use a different special character: %, &, +, or . (each of which may have special
considerations)
> # Reserve a block of IDs for internal use (say, 0-10 or 0-100), and move other tables
on upgrade
