Allen Wittenauer commented on HDFS-10653:
-----------------------------------------
bq. Do you have a clue why test results page is not available for the
branch-2.6 patches?
TL;DR: branch-2.6 support was removed from precommit.
Longer:
{code}
/usr/lib/jvm/java-8-oracle:1.8.0_101
/usr/lib/jvm/java-7-openjdk-amd64:1.7.0_101
{code}
As mentioned months and months ago on common-dev, JDK6 was jettisoned in favor
of JDK8 until Apache Yetus can support different settings per branch. In
addition, I have no idea what JDKs are in the branch-2.6 dockerfile, but given
that jdk8 is available, I'm guessing someone blindly backported a trunk patch
without considering the consequences.

> Converting a path String to a byte[][] currently requires an unnecessary
> intermediate conversion from String to String[]. Removing this will reduce
> excessive object allocation and byte copying.
