> The IndexScrutinyTool is doing full scans for index tables on multitenant tables.
> This is due to a change in PHOENIX-5089, where we added code to IndexColumnNames to skip a portion of the PK if the table is multitenant:
> https://github.com/apache/phoenix/commit/cc9754fff840f38d13c3adb0c963296959fff3fa#diff-0705645faa779229d00792c032ed377fR64
> This causes scrutinies for global, non-view indexes on multitenant tables to skip the tenantId when generating the pk column list, thereby causing a full scan.
