Sean Owen resolved SPARK-26985.
-------------------------------
Resolution: Not A Problem
Same as SPARK-26940; until it's reproducible on a standard JDK, I don't think
it's at all clear it's not due to this custom JDK implementation. I don't see
evidence it has to do with endian-ness.
> Test "access only some column of the all of columns " fails on big endian

> Key: SPARK-26985
> URL: https://issues.apache.org/jira/browse/SPARK-26985
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.3.2
> Environment: Linux Ubuntu 16.04
> openjdk version "1.8.0_202"
> OpenJDK Runtime Environment (build 1.8.0_202-b08)
> Eclipse OpenJ9 VM (build openj9-0.12.1, JRE 1.8.0 64-Bit Compressed
> References 20190205_218 (JIT enabled, AOT enabled)
> OpenJ9 - 90dd8cb40
> OMR - d2f4534b
> JCL - d002501a90 based on jdk8u202-b08)

> Reporter: Anuja Jakhade
> Priority: Major
> Labels: BigEndian
> Attachments: DataFrameTungstenSuite.txt,
> InMemoryColumnarQuerySuite.txt, access only some column of the all of
> columns.txt
>
>
> 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
> ***
