Thomas D'Silva commented on PHOENIX-1821:
-----------------------------------------

Looks good , one minor nit about the comment in testNonTxToTxTableFailure

{code}
+        try {
+            // This will succeed initially in updating the HBase metadata, but 
then 
+            conn.createStatement().execute("ALTER TABLE SYSTEM.NON_TX_TABLE 
SET TRANSACTIONAL=true");
+            fail();
+        } catch (SQLException e) {
{code}

> Transactional tables (in addition to any indexes) require a transformation to 
> the Cell timestamp (pending HBASE-8927 and some ideas of [~ghelmling]). In 
> addition, different coprocessors need to be installed on a transactional 
> table. We should have a mechanism to translate a table from being non 
> transactional to transactional.
