Hi Silas I did as you said, and it works, thanks a lot! as for cube level I config at Web UI for Cube level, below shows the details: kylin.source.hive.config-override.mapreduce.reduce.memory.mb = 1536 kylin.source.hive.config-override.mapreduce.reduce.java.opts = -Xmx1g
also thanks for Shaohui to make it clear -- BR Xixin At 2018-07-19 13:44:39, "Ge Silas" <go...@live.cn> wrote: Hi Xixin, Can you try to configure these memory settings in conf/kylin_hive_conf.xml?

I checked the MR log and the log shows that reducers containers is running beyond physical memory limits below is detail logs: Diagnostic Messages for this Task: Container [pid=50920,containerID=container_1518617687620_384770_01_000287] is running beyond physical memory limits. Current usage: 1.0 GB of 1 GB physical memory used; 2.6 GB of 2.1 GB virtual memory used. Killing container. then I try to overwrites the related config kylin.engine.mr.config-override.mapreduce.reduce.memory.mb = 4096 kylin.engine.mr.config-override.mapreduce.reduce.java.opts = -Xmx3g <http://apache-kylin.74782.x6.nabble.com/file/t746/%E5%B1%8F%E5%B9%95%E5%BF%AB%E7%85%A7_2018-07-19_11.png> then built the cube again, the the same error came again. I check the yarn config mapreduce.reduce.memory.mb = 2G. this is confused me. where kylin get the 1GB physical memory config limit? why the overwrites not work? -- Sent from: http://apache-kylin.74782.x6.nabble.com/
