Description

While running tests on Apache Spark v2.3.2 with AdoptJDK on big endian, I am observing test failures for 2 Suites of Project SQL.
1. InMemoryColumnarQuerySuite
2. DataFrameTungstenSuite
In both the cases test "access only some column of the all of columns" fails due to mismatch in the final assert.

Observed that the data obtained after df.cache() is causing the error. Please find attached the log with the details.

cache() works perfectly fine if double and float values are not in picture.

Inside test !!!!!!- access only some column of the all of columns *** FAILED ***
