Josh Elser commented on PHOENIX-3769:
-------------------------------------
bq. There are two implementations of function compareTo. In case of x86,
compareTo implemented by enum UnsafeComparer is executed whereas in case of
ppc64le, compareTo implemented by enum PureJavaComparer is executed. Josh Elser
looks like this is the root cause of this failure.
Ok, if that is broken, please spin out a JIRA issue for the HBASE project.
{{Bytes}} is an HBase class.
bq. I found another workaround for this issue. I noticed that the respective
lengths of the arrays are not passed to compareTo function. On making this
change, the test passes on ppc64le as well as x86.
Good find, [~skanekar]! That looks like a copy-paste bug to me. Want to attach
a new patch to this issue for this change only and see what the automated
testing says?
