Kazuaki Ishizaki updated ARROW-3476:
------------------------------------
    Description: 
Apache Arrow is becoming commonplace to exchange data among important emerging 
analytics frameworks such as Pandas, numpy, and Spark.

[IBM Z|https://en.wikipedia.org/wiki/IBM_Z] is one of platforms to process 
critical transactions such as bank or credit card. Users of IBM Z want to 
extract insights from these transactions using these emerging analytics systems 
on IBM Z Linux. These analytics pipelines can be also fast and effective on IBM 
Z Linux by using Apache Arrow on memory.

Since IBM Z Linux uses big-endian data format, it is not possible to use Apache 
Arrow in this pipeline. If Apache Arrow could support big-endian, the use case 
would be expanded.


When I ran test case of Apache arrow on a big-endian platform (ppc64be), {{mvn 
test}} in memory causes a failure due to an assertion.
In {{TestEndianess.testLittleEndian}} test suite, the assertion occurs during 
an allocation of a {{RootAllocator}} class.

On a big-endian platform, {{mvn test}} in memory causes a failure due to an 
assertion.
In {{TestEndianess.testLittleEndian}} test suite, the assertion occurs during 
an allocation of a {{RootAllocator}} class.
