--------------------------------------
Summary: Test failure on Big Endian
Key: IGNITE-10806
URL: https://issues.apache.org/jira/browse/IGNITE-10806
Project: Ignite
Issue Type: Bug
Affects Versions: 2.7, 2.6
Environment: Linux Ubuntu 16.04 Big Endian
Reporter: Namrata Bhave
{{Hi,}}
{{`*GridMessageCollectionTest.testMarshal->doTestMarshal*` from
`*IgniteBasicTestSuite*` fails with below error on *big endian platform*:}}
_{{[ERROR] testMarshal(org.apache.ignite.util.GridMessageCollectionTest) Time
elapsed: 0 s <<< FAILURE!}}_
_{{junit.framework.AssertionFailedError: expected:<115> but was:<29440>}}_
_{{at
org.apache.ignite.util.GridMessageCollectionTest.doTestMarshal(GridMessageCollectionTest.java:120)}}_
_{{at
org.apache.ignite.util.GridMessageCollectionTest.doTestMarshal(GridMessageCollectionTest.java:89)}}_
_{{at
org.apache.ignite.util.GridMessageCollectionTest.testMarshal(GridMessageCollectionTest.java:71)}}_
{{As per my analysis, this error occurs when proto is set to 1 in
[GridMessageCollectionTest.java|}}{{https://github.com/apache/ignite/blob/2.7.0/modules/core/src/test/java/org/apache/ignite/util/GridMessageCollectionTest.java#L74}}{{]
and test passes for proto=2.}}
{{While checking the implementation of
[DirectByteBufferStreamImplV2.java|}}{{https://github.com/apache/ignite/blob/2.7.0/modules/core/src/main/java/org/apache/ignite/internal/direct/stream/v2/DirectByteBufferStreamImplV2.java#L1422}}{{],
observed write/read methods are defined based on endianness and hence test
passes for proto=2. I tried making those changes in
DirectByteBufferStreamImplV1.java(for proto=1) and test passed. }}
{{I am not aware about the differences in the two protocol versions and their
implementation. Can the changes based on endianness be incorporated in v1 as
well? Could someone please help to resolve this? }}
