Hi Sungwoo??
Just want to confirm, does that mean I just need to update the hive version, without updating the hadoop version? Thanks!

Hive 3.0 make a few function calls that depend on Hadoop 3.x, but they are easy to replace with code that compiles okay on Hadoop 2.8+. I am currently running Hadoop 3.x on Hadoop 2.7.6 and HDP 2.6.4 to test with the TPC-DS benchmark, and have not encountered any compatibility issue yet. I previously posted a diff file that lets us compile Hadoop 3.x on Hadoop 2.8+. http://mail-archives.apache.org/mod_mbox/hive-user/201806.mbox/%3CCAKHFPXDDFn52buKetHzSXTtjzX3UMHf%3DQvxm9QNNkv9r5xBs-Q%40mail.gmail.com%3E --- Sungwoo Park On Thu, Jul 19, 2018 at 8:21 PM, ?????? <461292...@qq.com> wrote: Hi, I already deployed hive 2.2.0 on our hadoop cluster. And recently, we deployed the spark cluster with 2.3.0, aiming at using the feature that hive on spark engine. However, when I checked the website of hive release, I found the text below: 21 May 2018 : release 3.0.0 available This release works with Hadoop 3.x.y. Now the hadoop version we deployed is hadoop 2.7.6. I wonder, does Hive 3.0 only work with hadoop 3.x.y? Or, if we want to use hive 3.0, we have to update the hadoop version to 3.x.y? Looking forward to your reply and help. Best, Zhefu Peng
