fix LP 1347930 The main idea of the fix is as follows. 1. MC stats for compilation usage becomes multi-interval version, for key columns in a HBase table 2. MC stats stored in histogram cache now contains the multi-interval histogram.
LP bug 1413404, repository tables are inaccessible after upgrade. As part of upgrade, an internal 'initialize trafodion' stmt is issued which creates repository tables with salted columns. It also added salt expression string to TEXT metadata table. Objects that were created prior to this release did not have salt expression string in TEXT table. Upgrade code moves older salt expression from default field of columns table to TEXT table and updates text type. It was incorrectly updating text type of newly created respository tables that were already added to TEXT. Fix is to not update texttype if salt string has already been added.
