Major Description
Several tests failures related to schema evolution are happening on branch-2.1 due to a patch reverted in the past.

The problem is due to the following commits:
# This reverted patch about DECIMAL conversion to FLOAT and DOUBLE 6ab5f85299539aeb49bb02edfa142e4d4133f10e Revert "HIVE-13380 : Decimal should have lower precedence than double in type hierachy (Ashutosh Chauhan via Jason Dere)" ... # This added test cases for DECIMAL schema evolution d5285d8ebaf5bef2a13b2c2338be2fe683804b02 HIVE-12878: Support Vectorization for TEXTFILE and other formats (Matt McCline, reviewed by Sergey Shelukhin) ... # This added DECIMAL conversion to FLOAT and DOUBLE b507520e17811c8e059aa7d30490d29b984e2e96 HIVE-13380 : Decimal should have lower precedence than double in type hierachy (Ashutosh Chauhan via Jason Dere)
Because DECIMAL conversion is not supported on branch-2.1, then we should update the test cases and remove or update those tests causing the failure.
