jdk8 compatibility with hdp

about jdk8 compatibility - sorry for rising things from the grave but ....

can HDP 1.1.2.21 work with jdk8 ?

i am having issue with memory on map reduce jobs since we moved to jdk8,

like :

TaskTree [pid=13508,tipID=attempt_201709180208_0675_m_000000_0] is running beyond memory-limits. Current usage : 2583085056bytes. Limit : 1610612736bytes. Killing task.

is something in the mapred configuration should change , and if yes - what ?

Hi @yair fridman

I don't believe this would be a supported configuration. If I recall correctly, I don't think JDK8 support started until HDP 2.3. If you need to use JDK8, it would be best to upgrade Ambari/HDP to a much more recent version.
