Andrew Purtell updated HBASE-12995:
-----------------------------------
Description: [~jamestaylor] mentioned that recently Phoenix discovered at
some point the {{HConnection#getTable}} "lightweight table reference" methods
stopped throwing TableNotFoundExceptions. It used to be (in 0.94 and 0.96) that
all APIs that construct HTables would check if the table is locatable and throw
exceptions if not. Now, if using the {{HConnection#getTable}} APIs, such
exceptions will only be thrown at the time of the first operation submitted
using the table reference, should a problem be detected then. We did a bisect
and it seems this was changed in the 0.98.1 release by HBASE-10080. Since the
change has now shipped in 10 in total 0.98 releases we should just document the
change, in the javadoc of the HConnection class, Connection in branch-1+.
